ogg dev - Feb 2006 - Win64 problems

I am having problems with my program decoding .ogg files on the Win64 platform
and am wondering if this is a known issue or not.

I have tried using the prebuilt .dll's, the static .lib's and building
from source (1.1.3) and I get the same results.  My program is being compiled on
a win32 platform, but the decoder fails if I run it on a win64 system.

Unfortunately this is being reported by our offsite test group, so I don't
have access to the win64 machine to do any testing.  I have narrowed it down to
the OGG decoder, it has nothing to do with the actual playing of the sound.

I thought I'd see if there was a know problem before I go track down (or
buy) a win64 machine.

I can't build a special win64 version of my program, the one that ships for
the win32 platform needs to run on win64.

Well, I obviously do not have your program, but FWIW I don't have
problems on 64-bit Windows XP with Foobar 2000. It quite happily
decodes Oggs (Vorbis).
Or what do you mean with Win64?

I admit I haven't tried compiling Ogg or Vorbis for awhile.

* Check that everything is compiled either as 32-bit or 64-bit
   - mixing them is not allowed AFAIK.
* Compile everything with the same compiler version so that there
  are no obscure ABI format changes.
* Try without optimizations.

I wonder if there are inconsistencies with libogg vs. libvorbis
vs. vorbistools. I remember them at least one time using basic types
instead of ogg_* types (or int32_t, etc).
Of course that shouldn't affect binaries compiled with same
options, but mixed up types might produce funny results.
