Bug 2004

Summary: Calling Mix_Quit twice with midi support leads to segfault

Description Martin Gerhardy 2013-08-01 04:10:24 UTC 
the variable soundfont_paths is freed, but not set to NULL. So calling Mix_Quit a second time would crash if SDL_mixer is compiled with midi support. For all the other sound types, it's guarded with if (initialized). So i think it would be good to fix this by setting the soundfont_paths variable to NULL in line 231 of mixer.c
