I get a SIGSEGV when I press keys like Space, R or H but not with the arrow keys or Escape.
The mouse buttons work but not the wheel (no crash).
This happens with the AUR packages and the manual build.

I've done a bisect and c38a9ec is the offending commit. The parent commit does not crash and the wheel is functional.
This is the backtrace: gdb.txt

I have:
ffmpeg 2:8.0.1-2
sdl2-compat 2.32.62-1
sdl2_ttf 2.24.0-2
sdl3 3.4.0-2
