sdl2-compat: Calling Mix_CloseAudio() causes segfault (Arch Linux)

[sgpowers]

Arch Linux, at time of issue:

sdl2-compat 2.30.54-1
sdl2_image 2.8.4-1
sdl2_mixer 2.8.0-1
sdl2_ttf 2.24.0-1
sdl3 3.2.4-1

Mix_CloseAudio () is called once as the app exits, but even multiple calls should have no issue in SDL2.

There are no devices open as confirmed with SDL_GetNumAudioDevices(0) and various Mix_QuerySpec checks.

    Mix_CloseAudio();
    Mix_Quit();

    TTF_Quit();
    IMG_Quit();
    SDL_Quit();

gdb output below.

Thanks for the great work as ever.

I am guessing this is related to #313 - Apologies on the duplication if so.

I think it is related, but let's keep this open until that resolves in case we're wrong.
