Looks like -mnobitfield option increases object's size more than 100%. I don't
know if so big file size increase is correct. Another problem can be noticed
with GCC 4.4.2 which generated 45% bigger object than t

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 -

LOL! So you prefere to not get any bugreports? I reported a few bugs which were
next confirmed on the other hardware and after some time fixed, no matter if I

How's that possible? What about GCC 4.4 branch? I just checked with ATARI GCC
