Rust-clippy: unexpectedly panick when compiling mysql_common

Created on 13 Sep 2019 · 14Comments · Source: rust-lang/rust-clippy

Compiler panics when compiling mysql_common 0.18.0.

I tried to lint a project using mysql_common as dependencies using cargo clippy but I got the following error:

error: internal compiler error: src/librustc/ty/context.rs:516: node_type: no type for node `expr 5 (hir_id=HirId { owner: DefIndex(228), local_id: 255 })`

thread 'rustc' panicked at 'Box<Any>', src/librustc_errors/lib.rs:644:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.
error: aborting due to previous error


note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.38.0-nightly (8a58268b5 2019-07-31) running on x86_64-apple-darwin

note: compiler flags: -C debuginfo=2 --crate-type lib

note: some of the compiler flags provided by cargo are hidden

error: Could not compile `mysql_common`

I got the same error with the following Rust versions:

nightly-2019-08-01
nightly-2019-08-17
nightly-2019-09-11
nightly-2019-09-13

But it works with:

nightly-2019-07-19

L-bug L-crash

Hi,

with RUST_BACKTRACE=1

here is the repository to reproduce: https://gitlab.com/bloom42/phaser, just run make lint with one of the affected Rust versions

Please note it does not panic when compiling, just when clippy is 'checking'

I’m seeing this error in stable now when I run clippy. Haven’t localized it to a package yet. This may block us from adopting 1.38

EDIT: Host tuple x86_64-apple-darwin
