[MPlayer-users] bug report. assert failing

right, i encoded a film with mencoder and this si the first time it's ever
had any problems with the result. the output fails an assertion with
mplayer.
the problem seems to lie in the crop settings, i'm using:
mencoder -dvd 1 -alang en -oac mp3lame -lameopts abr:br=128 -ovc lavc
-lavcopts vcodec=mpeg4:vhq:vqmin=2:vbitrate=571 -vop
scale=-1:-2,crop=720:434:0:72
the system crashes when playing back the crop, and the assertion fails
from the scale command (when using proper values e.g. 640:360 as well)
if i remove both -vop options it is fine.
my system...
mplayer 0.90pre9 from source
athlon 1.2
mandrake 8.2 mostly
kernel 2.4.19
gcc 3.2
glibc 2.2.4
as 2.12.90.0.15
here is the output from gdb, although running the original compiled
binary (just unstripped?) from gdb plays the file fine. runnning that
binary normally fails, as does running the installed binary from gdb.

output from mplayer attached as mplayer.log logically enough.
i will now just go and upload the start of the file to erm...

oh and xine plays it! (just to wind you up into having a look)
chris, who's paranoid he's being deliberately ignored.
