I have seen this problem listed multiple times on the forum, but so far I do
not see an answer.
I have an OGG file that worked fine back with SDL_Mixer-1.2.5. With the
latest mixer I have a problem where it crashes in music_ogg.c at line 79:
0xC0000005: Access violation writing location 0x00000010
This is the code it crashes on:
if ( vorbis.ov_open(fp, &music->vf, NULL, 0) < 0 ) {
The vorbis structure appears to be filled out with pointers to the various ogg
dll functions.
Since Mixer 1.2.5 used a lib and not a DLL I assume that this is related to
the problem. I can provide a sample OGG file to demonstrate this bug. I am
using Visual Studio 2003. I saw another post where the person had the same
error and they were using Visual Studio 2005.

I have attached a short OGG file that demonstrates this crash using
SDL-1.2.11 and SDL_Mixer-1.2.7. Build the PLAYMUS sample app that is
included with SDL_Mixer and you will see that it crashes with the above
error when trying to play this OGG file._______________________________________________

As I thought, switching back to SDL_Mixer-1.2.5 works fine. There appears
to be a bug in SDL_Mixer-1.2.7 (or else I am doing something incorrectly).

It works fine for me on Mac OS X. I’m guessing it’s a C runtime incompatibility on Windows. If you build both SDL_mixer and playmus from source, do you see the problem? If so, can you run it in the debugger and find out what’s going on?
See ya!

Yes, it happens if I build it from source under Windows using Visual Stuido
2003 or VS2005.
This is the code it crashes on:
if ( vorbis.ov_open(fp, &music->vf, NULL, 0) < 0 ) {
The vorbis structure appears to be filled out with pointers to the various
ogg dll functions. The file point is a valid file pointer. In the actual
callback it appears to be crashing trying to do the fseek to the start of
the file. I will try changing the compile type from Multithreaded to single
threaded and see if it still crashes.
Any luck with that?
