Ok, good.

There aren't many ways to help us find the bug. You need to extract
the shortest possible sample (the shortest the better as that way we
don't have to wait for ages for the crash to happen) and upload it to
ftp://ftp1.mplayerhq.hu/MPlayer/incoming with a relevant name, such as
'avc4-crash-put_h264_chroma_mc4_mmx', and post a message  to ffmpeg's
development mailing list (the library we use to decode videos), with a
the name of the sample you uploaded.

Hopefully, the talented people there should be able to soon fix the bug.
