Flycast: Loading from terminal

[telanus]

If I load Naomi/AtomisWave roms from the terminal will fail with:

SIGSEGV @ 0x7fc196021105 (signal_handler + 0x0x1da02715) ... 0x7fc176d4aa08 -> was not in vram

Loading is done like:

retroarch -L "/Games/retroarch/cores/reicast_libretro.so" /Games/Romz/naomi/sortuit/spawn.zip

When I run it from inside RA it works but not loading it from terminal

[emersonnovais]

Yeah! I have the same issue too with Lubuntu 16.04 64 bits. My error message:

Note: "Instrução ilegal (imagem do núcleo gravada)" means in english "Illegal instruction (segmentation fault)" because my system is in portuguese.

[emersonnovais]

The error persists with Dreamcast games too. If the game is select from user interface of Retroarch, there is no error and the game starts normally.

[flyinghead]

I always launch retroarch using a command line and it works fine on my ubuntu 16.

I haven't updated my retroarch for a while so something might have changed there.
What retroarch version/commit are you running?

Also if you can run retroarch under gdb and give me the stacktrace when it crashes, it would be very helpful

[telanus]

Running Retroarch 1.7.5 GIT 978b581

[blisstik]

Can you guys try

retroarch < /dev/null -L /path/to/reicast_libretro.so /path/to/game.zip

This added < /dev/null and report back.

[telanus]

@6alileo still crashing: https://pastebin.com/hP1ANNw1

[flyinghead]

I still can't reproduce this on Ubuntu 16 with retroarch git 978b581 and latest core.

Are you sure you are running the same core and same content when running from the command line and when loading from within RA?

[telanus]

@flyinghead sorry that I only answering now, Busy time at work.

Yes the same core is used, I have my cores living under /Games/retroarch/cores and have setup retroarch to use it. I'm using RetroArch 1.7.5 (Git bd2fb04) (cloned & self-compiled this morning) and reicast is Git-37da602 also cloned & compiled this morning

[emersonnovais]

Unfortanelly the error persists and I cann't test the MAME versions of Atomiswave and Naomi. :(

[flyinghead]

I still have no idea what's going on here. Can you build the core with symbols (-g) so we get a stack Trace?

[telanus]

Hi @flyinghead compiled a debug version (make complained -g doesn't exist, I used DEBUG:= 1) and got this when using gdb

Here is a paste of everything from the run command: https://pastebin.com/PPrmSGQX

[barbudreadmon]

@telanus What's your cpu ? I think we had a similar issue in the past and it was related to cpu instruction set

[telanus]

@barbudreadmon It's a Dual-Core E5300.

[flyinghead]

Ok, this SIGSEGV is normal.
You need to run this gdb command before running RA:

handle SIGSEGV nostop noprint

[telanus]

OK, weird.

@flyinghead using that command it'll load up to this screen:

this is the output I get on the terminal:

[flyinghead]

Which game are you trying to load? Which type (cdi, gdi, chd)?
If you run the exact same command without gdb do you get a crash?

[telanus]

@flyinghead I tried loading a mix of games (Crazi Taxi, Virtua Tennis, Dead or Alive 2, Ikaruga, Marvel Vs Capcom 2) mostly in the cdi format, but Ikaruga is gdi.

And yes it crashes when loading via terminal (without gdb)

Haven't tried chd so far

[telanus]

OK Just tried a chd, and it throws the same error

[flyinghead]

I suppose this is a random issue that doesn't crash when run in the debugger... bummer

I'm experiencing an issue that could be the same one but it happens once every 100 runs or so, and never with gdb.

I guess you can try multiple games and hope that one will crash...

[flyinghead]

Actually, there's something to try;
In the Makefile, replace the line OPTFLAGS := -O0 with OPTFLAGS := -O3 and do a full rebuild.

[telanus]

@flyinghead I tried that and it didn't work :'(. Same error

[emersonnovais]

The error persist buts in the line 398 of core/libretro/common.cpp

Try to run this under gdb to get a stack trace.

I have what I think is the same problem on my machine. But it happens only once every 100 runs and never when debugging. I've spent another couple of hours on this problem to no avail.

So I'm going to need some help to make progress.

[telanus]

@flyinghead hope this is OK:

[emersonnovais]

@flyinghead, if I clean up my settings folder and the configurations files the error will end or will persists? Thanks.

[flyinghead]

@emersonnovais I doubt this problem is related to your settings but trying with fresh/default settings isn't going to hurt either and will give us the confirmation.

[telanus]

@emersonnovais I tried removing ./config/retroarch and still have the same problem

[flyinghead]

@telanus the log you posted is showing a different problem than the initial one, and not the bug I'm chasing.

This is what I'm looking at:

Try rebuilding with DEBUG=1 so we'll have symbol names in the stack trace.

@telanus, have you removed the flash files in /dc/data and /dc files like dc_nvmem.bin, flash.bin and the vmu files? I can't made this now because I'm going to working and will come later.
Thanks.

I made a test removing the flash and vmu files and the errors persists.

This seems to have disappeared with the merger of the two cores.

The random crash I was sometimes having at startup seems to have disappeared as well.

Feel free to close the issue.
