Vorbis dev - Jul 2001 - win32: Encoder using vorbisenc.dll - AV?

Hello,

When I compile either oggenc or encoder_example with static libraries, they 
work fine, but when I try them with the dynamic libraries, I get an access 
violation in vorbisenc.dll with both oggenc and encoder_example. Can anyone 
on win32 confirm this?

It's strange because vorbisfile.dll *does* work with vorbisfile_example, 
and the configuration for vorbisfile.dll is exactly the same (only the 
names are different.)

I guess it can't be a problem in the source because static linking works 
OK, but if vorbisfile does work dynamically with the same config as 
vorbisenc, it is a MSVC problem perhaps?

You may be mixing singlethreaded (in oggenc and the examples) and
multithreaded (in the vorbis dlls) C runtime libaries. Please turn off
any /NODEFAULTLIB options, and check if you get warnings about libc,
libcmt and such like.

I always use my own VC project files to compile all vorbis programs
(since the project files in the CVS repository seem quite broken), and
they all work without problems, either static or dynamic. If you like,
I can send you my project files.

Cheers,

Jack believes we've discovered the problem here...

In a number of places, we're keeping function calls in static arrays
that are passed from module to module.  I'm relating the following
second-hand, (and I'm not a win32 developer ;-) so I may be
misremembering slightly, but these arrays being marked as 'data'
rather than 'code' in the project file is causing the trouble.

Jack/Mike, please jump in here and prevent me from sounding any more
like an idiot.
