Hi,

FFmpeg compiled with GCC 4.5 (20090827) crashes when I try to convert mpg file
to avi (divx). 

"FFmpeg_020fpu -i test.mpg test.avi"

1. I get crash only with "-m68020 -m68881" options, not with -m68040 or
-m68060.
2. I get crash only with -O1, -O2 or -O3 options, not with -O0.
3. GCC 4.4.2 (20090825) don't have this problem.

The problematic file is "libavcodec/ratecontrol.c" - this file generates crash.
I include preprocessed file from GCC 4.4.2 and GCC 4.5.0.
