Can you please build SDL and your test app with debug symbols and provide a crash stacktrace?
cmake .. -DCMAKE_BUILD_TYPE=Debug
cmake --build . --target SDL3-shared
gcc -o testapp -g src.c libSDL3.so -I ../include -Wl,-rpath,$PWDThen run your app in gdb as gdb ./testapp.
Inside gdb, start executing with the command run.
When you get it crashing, print a stacktrace with bt.
from sdl.

I've tried gdb ./testapp -ex=run 20 times and finally
build$ gdb ./testapp -ex=run

Can you get backtraces for the other threads?

And please also install debug symbols for pipewire and other libraries you see in the traces.

hmm... Looks like libpipewire-0.3-0-dbgsym and libspa-0.2-modules-dbgsym are only available for unstable Debian, or maybe I'm searching wrong

Yeah, we'll need symbols for pipewire to see what's going on here. From what you've shown it looks like a random crash in pipewire, which could either be a bug in SDL or a bug in pipewire.
It might also help to run with address sanitizer to make sure nobody is touching uninitialized memory.

Ok, I've used debuginfod, that downloaded a lot of stuff including pulseaudio, pipewire, and spa
But seems like nothing has changed. Should I use other command?
