[SDL] SDL_mixer1.2.7 - MP3 playback is unstable on WinXP...

"Find out exactly where the crashes occur. This is fairly easy with

Crash occurs sometimes (maybe 1 out of 10 runs) in the following SDL_mixer  
functions:
"Mix_OpenAudio"
"Mix_PlayMusic"
"Mix_CloseAudio"
 
when 
Mix_OpenAudio(MIX_DEFAULT_FREQUENCY, MIX_DEFAULT_FORMAT,    
MIX_DEFAULT_CHANNELS, 1024)

Program locks-up (not responding).

Find out  exactly where the crashes occur. This is fairly easy with 
Visual Studio.  My guess is that the crashes are inside  smpeg.
