------- Comment #11 from ami_stuff at o2 dot pl 2010-01-02 00:41 -------
The problematic function is as was said "ff_rate_estimate_qscale".
I found out which optimizations causes the problem:
-m68020 -m68881 -O1 -fno-tree-ccp -fno-tree-dominator-opts (works ok).
-m68020 -m68881 -O1 ("Abort trap")
I attache output files from GCC 4.5 20091224. Maybe someone will try to create
a simpler testcase for thie bug in the future. GCC 4.4 and all older versions
of GCC works correctly, so bug was introduced in the GCC 4.5 branch (only for
-m68020/30 -m68881, -m68040 & -m68060 seems to be OK).
