Segmentation fault on renderer creation with WSLg
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.conf with the following content then restarting the WSL session solves the problem (source):
# Type Path Mode UID GID Age Argument
L+ /tmp/.X11-unix - - - - /mnt/wslg/.X11-unix
However the program still shouldn't have segfaulted, and should have just printed Couldn't create the renderer: xyz then exited.
A minimal program to produce the crash is the following:
sdl2_crash.c
/* Compile with `gcc sdl2_crash.c -g $(pkg-config sdl2 --cflags --libs)` */
#include <SDL.h>
int main() {
int ret = 1;
int sdl_initialized = 0;
SDL_Window *window = NULL;
SDL_Renderer *renderer = NULL;
SDL_Texture *texture = NULL;
SDL_Event event;
Uint32 *pixels;
int pitch;
int i;
if (SDL_InitSubSystem(SDL_INIT_VIDEO | SDL_INIT_EVENTS)) {
fprintf(stderr, "Failed to initialize SDL: %s\n", SDL_GetError());
goto fail;
}
sdl_initialized = 1;
window = SDL_CreateWindow(
"renderer crash on WSL",
SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED,
128,
64,
0
);
if (!window) {
fprintf(
stderr,
"Couldn't create the window: %s\n",
SDL_GetError()
);
goto fail;
}
/* Then let's create the renderer. */
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_SOFTWARE);
if (!renderer) {
fprintf(
stderr,
"Couldn't create the renderer: %s\n",
SDL_GetError()
);
goto fail;
}
texture = SDL_CreateTexture(
renderer,
SDL_PIXELFORMAT_ARGB8888,
SDL_TEXTUREACCESS_STREAMING,
128,
64
);
if (!texture) {
fprintf(
stderr,
"Couldn't create the texture: %s\n",
SDL_GetError()
);
return 1;
}
SDL_LockTexture(
texture,
NULL,
(void **)&pixels,
&pitch
);
for (i = 128 * 64 - 1; i >= 0; i--)
pixels[i] = 0xFF0000;
SDL_UnlockTexture(texture);
SDL_RenderCopy(renderer, texture, NULL, NULL);
SDL_RenderPresent(renderer);
while (SDL_WaitEvent(&event)) {
if (event.type == SDL_QUIT) {
ret = 0;
break;
}
}
ret = 0;
fail:
if (texture)
SDL_DestroyTexture(texture);
if (renderer)
SDL_DestroyRenderer(renderer);
if (window)
SDL_DestroyWindow(window);
if (sdl_initialized)
SDL_QuitSubSystem(SDL_INIT_VIDEO | SDL_INIT_EVENTS);
return ret;
}

Originally reported on Cahute as issue #57.
Do you have a call stack for the crash? Valgrind is pointing out coding errors in the WSL D3D code, which we can't do anything about.
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:

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.
That isn't a crash call stack though... ?
gdb doesn't prompt any crash while the minimal script is running, so I can't get the crash call stack atm.
Update: I was able to reproduce the result that prompts segfault explicitly:

@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?
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.
@0v0katai, can you apply this patch and send us the output?

With the latest verison of SDL2, the SDL2 minimal program now outputs Failed to initialize SDL: No available video device as well. ~~Seems like the memory leak is fixed.~~
(Edit 2025-6-24: Sorry for misinformation. It turns out I was using sdl2-compat which is actually based on SDL3 codebase. I manually built the the latest verison (2.32.8) of SDL2, and used gcc sdl2_crash.c -g $(sdl2-config --cflags --libs). The result is still a segfault.)
