[Ffmpeg-devel] FFMPEG crashes on WinXP SP2

Hi all, this is my first post.

I am trying to use FFMPEG to decode some ASF files under Windows and I'm 
having trouble. It crashes every time on Windows XP SP2 but works fine 
on WinXP SP1.

Most other video formats seem to work fine, just not ASF.

I have tried versions 0.4.8, 0.4.9-pre1 and the latest CVS, they all 
exhibit the same problem.

I compiled FFMPEG with MinGW using --enable-mingw32 --enable-shared 
--disable-static --enable-memalign-hack

Here is an example of how to crash it (using version 0.4.8):

C:\Program Files\FFmpeg> ffmpeg -i test1.asf test1.mpeg
input #0, asf, from 'test1.asf':
  Duration: 00:01:14.9, bitrate: 599 kb/s
  Stream #0.0: Audio: wmav2, 48000 Hz, stereo, 128 kb/s
  Stream #0.1: Video: wmv2, 352x240, 15000.00 fps
Output #0, mpeg, to 'test1.mpeg':
  Stream #0.0: Video: mpeg1video, 352x240, 15000.00 fps, q=2-31, 200 kb/s
  Stream #0.1: Audio: mp2, 48000 Hz, stereo, 64 kb/s
Stream mapping:
  Stream #0.1 -> #0.0
  Stream #0.0 -> #0.1

That will crash, however if I use the -an option to disable audio 
processing, it does not crash.

I've had a go at trying to debug it but the code is difficult for me to 

Has anyone else had such problems ?
