Description Sebastian Beschke 2006-06-07 17:05:42 UTC
Using the prebuilt SDL_mixer DLLs, SDL_mixer 1.2.7 crashes with an access violation upon trying to load an OGG Vorbis file using Mix_LoadMUS().

Here's a small sample program:



#include <stdio.h>
#include "SDL.h"
#include "SDL_mixer.h"

int main(int argc, char* argv[])
{  
   fprintf(stderr, "SDL_Init(SDL_INIT_AUDIO);\n");
   SDL_Init(SDL_INIT_AUDIO);
   
   fprintf(stderr, "Mix_OpenAudio\n");
   if(Mix_OpenAudio(22050, AUDIO_S16SYS, 2, 4096)) {
      fprintf(stderr, "OpenAudio failed: %s\n", Mix_GetError());
      exit(1);
   }

   
   fprintf(stderr, "Mix_LoadMUS()\n");
   Mix_Music* music = Mix_LoadMUS("music.ogg");
   if(!music) {
      fprintf(stderr, "Could not load music.ogg: %s\n", Mix_GetError());
      exit(1);
   }
   
   fprintf(stderr, "Mix_FreeMusic()\n");
   Mix_FreeMusic(music);
   
   Mix_CloseAudio();
   
   SDL_Quit();
   
   return 0; 
}

This is working on Linux (and Valgrind doesn't smell anything fishy)...perhaps we fixed it? A broken ogg? Perhaps it's a Windows-specific thing or a misbuilt library?

Tossing it to Sam.

The OGG file I used was fine; the problem occured for me on Windows XP and has been reproduced by several people (using the pre-built DLLs).

I can reproduce the problem as well, I'm looking into it.
Comment 4 Sam Lantinga 2006-06-26 13:43:02 UTC
This was caused by a C runtime mismatch.  This is fixed in subversion, and you can get the updated 1.2.7 files here:
