Comment (by cyril):

 I've attached what I used to test in MinGW. I simply replaced ffmpeg.h/.c
 with something similar to JpegTest.cpp, compiled FFmpeg with MinGW, and
 reproduced the bug with the resulting ffmpeg_g.exe.
 I'll try to test this on Ubuntu and see if the bug is also reproducible
 there.
