After your explanation of the SVGAlib case, I checked: the problem is not the
same. After some tests, it appears the arts module is unloaded *after* the call
to remove_sound(). And I double checked, even if I disable module unloading for
arts, the crash still happens.

The problem is similar, though. Arts registers its own shutdown function with
atexit, and does so *after* allegro has registered allegro_exit with atexit
(because install_sound is called *after* allegro_init). The result is that when
the program ends, arts shuts itself down, and *then* allegro tries to
remove_sound(), making the program crash.

Yes, but I tried and unfortunately leaving the module in memory doesn't help.

Anyway, the patch I sent Works For Me (TM) :-). But it register itself again
with atexit every time the sound is installed. I can make it register itself
only once, but then it relies on the fact that arts itself registers itself only
once.
