Hi!

Trying to encode a video, I consistently run into the following crash:

Program terminated with signal 11, Segmentation fault.
#0  0xb7f0d266 in x264_pixel_satd_8x8_sse2 () from /usr/lib/libx264.so.58
(gdb) bt
#0  0xb7f0d266 in x264_pixel_satd_8x8_sse2 () from /usr/lib/libx264.so.58
#1  0xb7ebef5e in x264_slicetype_mb_cost () from /usr/lib/libx264.so.58
#2  0xb7ebf248 in x264_slicetype_frame_cost () from /usr/lib/libx264.so.58
#3  0xb7ec0c81 in x264_rc_analyse_slice () from /usr/lib/libx264.so.58
#4  0xb7ede286 in ?? () from /usr/lib/libx264.so.58

This happened with both r736 (from the debian multimedia repository) and
r745 (custom-compiled), machine is an Core 2 Duo T7200. libx264 was driven
by mencoder 1.0rc2 svn from december (recompiled against the current
libx264, of course) which works fine with older libx264s (r714 from the
debian multimedia repository, in paticular). Compiler was Debian's gcc
4.2.3.

Do you need any further information? I could recompile with debugging
symbols enabled if neccessary.

Greetings,

  Gunter
