SDL crashing with ALSA

Using the hatari emulator, I was experiencing crashing at a certain point.
The hatari author and myself traced it down to
SDL_InitSubSystem(SDL_INIT_AUDIO). It works the first time, but if you
make changes in the menu, hatari will shutdown the SDL audio subsystem, and

I did further testing and found that the crashing will only happen if
SDL_CloseAudio() gets called first. When I comment out SDL_CloseAudio(),
there’s no problem with SDL_InitSubSystem(SDL_INIT_AUDIO).

The code normally works fine on most systems. The system I’m having a
problem on happens to use the ALSA drivers, which I suspect might be a

Here is test code that will cause the SDL crash to occur. I realize I don’t
have a corresponding SDL_OpenAudio(), but the hatari code does.
