    /* Allocate the chunk memory */
     chunk = (Mix_Chunk *)SDL_malloc(sizeof(Mix_Chunk));
     if ( chunk == NULL ) {
      SDL_SetError("Out of memory");
      if ( freesrc ) {
       SDL_RWclose(src);
      }
      return(NULL);

      case WAVE:
      case RIFF:

         (Uint8 **)&chunk->abuf, &chunk->alen);

      case FORM:
       loaded = Mix_LoadAIFF_RW(src, freesrc, &wavespec,
         (Uint8 **)&chunk->abuf, &chunk->alen);
       break;
    #ifdef OGG_MUSIC
      case OGGS:
       loaded = Mix_LoadOGG_RW(src, freesrc, &wavespec,
         (Uint8 **)&chunk->abuf, &chunk->alen);
       break;
    #endif
    #ifdef FLAC_MUSIC
      case FLAC:
       loaded = Mix_LoadFLAC_RW(src, freesrc, &wavespec,

      case CREA:
       loaded = Mix_LoadVOC_RW(src, freesrc, &wavespec,
         (Uint8 **)&chunk->abuf, &chunk->alen);
       break;
      default:
       SDL_SetError("Unrecognized sound file type");

       SDL_free(chunk);  // This line is added
       return(0);   
     }

    //SOME CODE

}

In this code chunk memory is dynamically allocated,
but in default case of switch(magic), it's getting leak.

So it is important to free this chunk memory. Patch is shown in the above code with a comment // This line is added.
