Thank you very much for reporting this.

From the backtrace, it looks like this happens within the oniguruma library (written in C). To verify this, you could try to run bat … | cat such that bat does not use syntax highlighting (which should work without a segfault).

Are you sure that this happens for each and every input? What about something really simple like the following?

echo test | bat

or

echo '<test arg="1"></test>' | bat -l xml

[davidarmstronglewis]

The above all segfault, I'm not sure how to completely disable syntax highlighting however.

Would echo hi | bat --color never be sufficient? Because that segfaults as well with the following backtrace:

Would echo hi | bat --color never be sufficient?

No, but I would have assumed that

echo hi | bat | cat

should work (assuming cat is not aliased to bat :smile:)

In any case, I don't think there is much we can do here (except maybe roll back our dependencies). We need to report this upstream (in syntect or onig, or even oniguruma).

If possible, it would be great if you could clone https://github.com/trishume/syntect and run

cargo run --release --example=syncat …

on a simple file.

[jcstange]

Not sure if it's regarding the same problem, but just updated to Catalina and
echo hi | bat
returns the same segmentation fault as @davidarmstronglewis reported

[sharkdp]

I did a little research and found that there are a few reports about programs suddenly segfaulting with EXC_BAD_ACCESS.

This ffmpeg bug report has an interesting comment:

For context (don't know if it's related or not), this is the first macOS release that will no longer run ANY 32-bit code.

Maybe there are some low-level operations in oniguruma which are not supported anymore.

Could one of you please try to run some example programs from oniguruma?

git clone https://github.com/kkos/oniguruma
mkdir oniguruma/sample/build
cd oniguruma/sample/build
cmake ..
make

# run examples like:
./count

[sharkdp]

There are also some interesting things going on with bitwidths in the build.rs script in onig_sys (the Rust wrapper around oniguruma):
https://github.com/rust-onig/rust-onig/blob/1de4269744c23c8f59d3335077213f85e0a29e18/onig_sys/build.rs#L87-L116

I would look into it myself, but I don't have a macOS machine or a Catalina image which I could run in a VM.

[uraimo]

Could one of you please try to run some example programs from oniguruma?

The samples work on Catalina for all the version I've tried of oniguruma (master, 6.9.3(latest), 83572e983928243d741f61ac290fc057d69fefc3).

While I can't add much on the cause behind the crash, a thing I've noticed is that the latest version of rust-onig (v5.0.0) still points to oniguruma:83572e983928243d741f61ac290fc057d69fefc3 from April 23rd, way older than the latest release 6.9.3 tagged in August (and that contains fixes for two CVEs and a lot of fixes found by a fuzzer).
Master right now is pointing to oniguruma:565e5f43c2f9fb9905819ca3eb76114aea267890, 21st of August and there has been quite a few commits since that date too.
Maybe someone could test a modified version of the rust wrapper?

[kevinnio]

Maybe someone could test a modified version of the rust wrapper?

Ok, so I:

• Cloned rust-onig
• Updated oniguruma submodule to latest release
• Build bat using local clone for onig and onig_sys crates.

➜ bin/bat -p test.rb
[1]    95207 segmentation fault  bin/bat -p test.rb

The issue remains.

[kevinnio]

On the other hand, updating the oniguruma submodule to master and compiling produces a working binary!

➜ bin/bat -p test.rb
#! /bin/usr/env ruby

class HelloWorld
  def run!
    puts "Hello world!"
  end
end

HelloWorld.new.run!

[ryenus]

BTW, bat --list-themes also crashed with bat version 0.12.1.

$ bat --list-themes
Theme: 1337

Segmentation fault: 11

[jan-auer]

bat v0.11.0 does not crash (installed via Homebrew as 0.11.0_1 in my case). That version was still running onig 4.x.

[mkYYY]

According to this post, -fstack-check is the default option given to clang for macOS 10.15.x. I'm not sure if this affects rustc used to compile bat, however the disassembly of match_at function contains a function call to ___chkstk_darwin, which was added by the above option in clang.

% bat --version
bat 0.12.1
% otool -xvV /usr/local/bin/bat | grep "^_match_at:$" -A512
...
00000001000d65b3    callq   0x1002a0402 ## symbol stub for: ____chkstk_darwin
...
00000001000d6852    jmpq    *(%r10)
...

I ran bat on LLDB, and found that the value of r10 register was overwritten to a pointer to somewhere on the stack (0x7FEF...) during the function call (or during the dynamic binding). Then, the CPU continues execution and tries to jmp to a non-executable stack, so SIGSEGV occurs.
I overwrote bat binary itself to substitute 5-byte callq 0x1002a0402 instruction into nop; nop; nop; nop; nop. Then, bat successfully read the input from stdin (or pipe).

I believe bat works fine if we can elminate calls to ___chkstk_darwin (as a temporary workaround, at least). I'm completely new to rust, but is it possible to disable -fstack-check option or similar in rustc?

[eth-p]

@mkYYY That's an interesting finding. The code responsible for building oniguruma is here in the onig_sys crate. I believe it would be possible to add an option to disable -fstack-check somewhere in there.

I would recommend opening an issue with your findings there as well, since they apply to the onig crate and can be used to provide a workaround for other projects that use it.

---

@mkYYY @sharkdp Would a temporary solution
for Catalina users be to compile it on an older version of macOS and copy it over?

---

As a side note, I'm curious why -fstack-check is clobbering r10. If I remember correctly, it should be a caller-saved register. Is it not being saved before the call to ___chkstk_darwin?

[mkYYY]

@eth-p Thanks for the reply. I'm going to open it soon.

[BirkhoffLee]

@jan-auer Could you share how to install 0.11.0_1 via homebrew? I've tried the followings without luck :(

$ brew install [email protected]_1
$ brew install [email protected]
$ brew install [email protected]

[BirkhoffLee]

Never mind, downloaded https://github.com/sharkdp/bat/releases/download/v0.11.0/bat-v0.11.0-x86_64-apple-darwin.tar.gz and replaced /usr/local/bin/bat with it

FWIW, uninstalling the bat bottle and reinstalling from source (0.12.1) seems to have cleared up the segfault problem for me on MacOS Catalina (10.15.1).

brew uninstall bat
brew install -s bat

[eth-p]

@joevo Good to know that works. I suppose that means it's fixed upstream?

[BirkhoffLee]

Just tried it and it’s still segfault’ing on my side.

r10 is call-clobbered (== caller-saved) register according to x86-64 SYSV ABI, which macOS follows. Thus, it's caller's responsibility to save its value before it calls another function. In theory, compilers should emit the code to save r10 if it notices the register is going to be overwritten.

---

One thing I need to correct is that this odd behaviour is not because of ___chkstk_darwin, but due to dyld's resolution of lazy symbol pointer to ___chkstk_darwin. I continued debugging with LLDB and discovered r10 was clobbered during the lazy binding step.
Then I tried to force dyld to bind lazy symbol pointers at load time by setting special environment variable DYLD_BIND_AT_LAUNCH. Voila, bat was executed without errors!

Unfortunately, if the root cause is in dyld, there are little things we can do to fix them. IMO, compilers cannot know dyld's such behaviour, so that it does not emit code which saves r10 on compilation.
If so, until @[a]pple fixes the problems, we can copy from builds for older macOSes or build from source as @joevo mentioned (I don't know why the latter also works though).

[archite]

I added the following to the brew recipe:

ENV.append "RUSTFLAGS", "-Clink-args=-Wl,-bind_at_load"

Appears to be what was needed.

[skgsergio]

@archite Great! Did you PR or opened an issue on brew?

[archite]

I added #46770 to Homebrew/homebrew-core.

[fxcoudert]

Hi, Homebrew maintainer here. We've had a lot of trouble with Xcode 11's default stack-check, and the root issue is that Xcode 11's clang produces invalid code with this option. Apple is aware and should fix it, but the fix didn't make it in Xcode 11.2.

dyld is indeed involved in the process, but the root cause is really the -fstack-check. Even when the dyld code path is changed by using -bind_at_load, the issue can appear in other code paths (we've seen it in 23 packages so far out of 4000 in Homebrew).

[philFernandez]

FWIW, uninstalling the bat bottle and reinstalling from source (0.12.1) seems to have cleared up the segfault problem for me on MacOS Catalina (10.15.1).

brew uninstall bat
brew install -s bat

This fixed the issue for me, and as a side bonus I now have rust installed

[archite]

I've updated the PR. This works well and appears to be more standard across home-brew core.

ENV.append_to_cflags "-fno-stack-check" if DevelopmentTools.clang_build_version >= 1010

[edmondburnett]

Just tried it and it’s still segfault’ing on my side.

Same here, but then I updated Xcode to 11.2.1 and now reinstalling from source works.

[sharkdp]

Is there anything left to be done within the bat repository directly? Or can this be closed?

Edit: probably can not be closed, as I would expect this to still fail when someone is using cargo to install bat?

[archite]

@sharkdp Homebrew has been updated so it can be closed.

[davidarmstronglewis]

Had to reinstall bat via Homebrew, but it seems the issue has been fixed. Closing this issue.
