Hello,

Recent mencoder exits with sig 11 while encoding the 301st frame of
test.avi (to be found in
http://www.phys.uu.nl/~snel/mencoder_sig11.tar.bz2 ).
MMX, 3dnow disabled. Shortened GDB log attached, full GDB log included in
.tar.bz2. Using the contents of the .tar.bz2 the bug should be
reproducible.

Commandline:
mencoder -ovc lavc -lavcopts \
vcodec=mpeg4:vqmin=2:vbitrate=2050:vmax_b_frames=2:keyint=132:vlelim=-4 \
~/capture/test.avi -o ~/capture/columbo2.avi

With bitrate 1050 -> no segfault
without vlelim=-4 -> no segfault
without keyint=132 -> no segfault
without vmax_b_frames=2 -> no segfault
segfault also depends on input (slightly different test.avi (with
noisereduction , for example, moves segfault to arround 2000th frame)

Distribution: LFS
Kernel 2.4.18
libc 2.1.3
gcc 2.95.3
ld 2.10 (with BFD 2.10)
as 2.10
Processor: AMD K6-2 @350MHz (however, bug occurs with --disable-mmx 3dnow)

I hope someone (probably Michael) can reproduce/meditate and fix. Let me
know if more information/experimentation is needed.

Thanks,

Rik.
