Comment (by qyot27):
I've been trying to get to the bottom of this, but I'm not getting
anywhere. The crash happens in DllMain whenever a source filter
(AVISource, DirectShowSource, FFMS2, etc.) is used, but the reason why it
only affects 2.5.8 is a mystery to me.
Based on the observation that x264 can handle 2.5.8 without issue, and
that it's been using dynamic loading for AviSynth since November 2009, I
tried to shuffle things around in libavformat/avisynth.c to more closely
match how x264's input/avs.c is organized, but it just ends in segfaults
(what I managed to do is in the 'avsfix' branch on Github:
https://github.com/qyot27/FFmpeg/commits/avsfix).
