1 month ago Run your program under gdb, and type bt when it crashes?

1 month ago Still trying to reproduce the issue on local setup, and got feedback on the behalf of my contributor today. They tested with valgrind again, I pointed out you suggested using gdb with bt and I did not get an answer for this specifically yet.
In the mean time, they managed to encounter other crashes in slightly different configurations:

1 month ago Hi, I'm the original reporter of this issue. I apologize for not using gbd when @thomas-touhey commented because I got different valgrind results the next day and I had to set up another ArchWSL instance to reproduce the initial result. Right now this is what gdb gives me:
The minimal script didn't seem to trigger crash but gbd stopped at [New Thread 0x7fff3b7fe6c0 (LWP 4780)], and I had to interrupt manually to get the call stack info.

gdb doesn't prompt any crash while the minimal script is running, so I can't get the crash call stack atm.

1 month ago Update: I was able to reproduce the result that prompts segfault explicitly:
Then I ran it immediately with gdb. This time gdb stopped when segfault occured:

1 month ago @Kontrabant, it looks like this is crashing in WAYLAND_xkb_context_new() with a NULL pointer. Aren't we checking that symbols were successfully loaded before calling that?
Kontrabant
commented
1 month ago Yes, the first thing Wayland_CreateDevice() does is load the Wayland symbols, including the xkb library. That symbol is non-optional, so loading the Wayland driver should fail if it can't be found.

1 month ago Thanks @thomas-touhey. The SDL3 minimal script no longer segfaults and outputs the following message:

1 month ago This looks correct, thanks!
With SDL2, creating a software renderer using
SDL_CreateRenderer(window, -1, SDL_RENDERER_SOFTWARE)causes a segmentation fault on ArchWSL with WSLg on WSL 2, while the expected behaviour would (probably) be to fail with an error.As found by the original issue reporter, creating
/etc/tmpfiles.d/wslg.confwith the following content then restarting the WSL session solves the problem (source):However the program still shouldn't have segfaulted, and should have just printed
Couldn't create the renderer: xyzthen exited.A minimal program to produce the crash is the following:
sdl2_crash.c
```c /* Compile with `gcc sdl2_crash.c -g $(pkg-config sdl2 --cflags --libs)` */ #includeWhen run with
valgrind --leak-check=full --num-callers=500 ./a.out, the following output is created:valgrind report of the crash
