[MPlayer-dev-eng] mencoder crash with dct motion estimation (cmp=3:subcmp=3:mbcmp=3 )

[DD DD]

Hi
mencoder (cvs trunk 07/24/2006) is segfaulting with libavcodec if I use
cmp=3:subcmp=3:mbcmp=3 as motion estimation. Is there something wrong with
this ?
Surprisingly, it works if its compiled with debug on (--enable-debug=1)

./mencoder -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames
-quiet -of lavf -ffourcc FLV1 -ovc lavc -lavcopts
vcodec=flv:vbitrate=256:v4mv:mbd=2:trell:cmp=6:subcmp=6:mbcmp=6  -oac
mp3lame -srate 22050 -lameopts preset=64:mode=3 ia.mov -o ia.flv

Any ideas?
