I have one, perhaps a different bug, play
ftp://ftp.mplayerhq.hu/MPlayer/incoming/ff-coredump.avi with mplayer
(it's small, only 32k), it dumps with SIGFPE in h263.c.  It works if I
apply the attached trivial patch (which fixes the symptom, not the
disease).  The file works with ffplay.  With mplayer, I get this
warning at the start, just before the coredump:

 [mpeg4 @ 0x8703220]hmm, seems the headers are not complete, trying to guess time_increment_bits
 [mpeg4 @ 0x8703220]my guess is 15 bits ;)
