#4497: Segfault when using 'segment' format

Summary of the bug: Consistent segfault when using the 'segment' format.
It looks like everything's going fine for a little while but then it
segfaults. I don't think the inputs are affecting it because I've tried
with different inputs (files) and it still occurs. Maybe it's one of the
segment_* option modifiers.
How to reproduce:
{{{
% ffmpeg -f alsa -i hw:0 -f video4linux2 -s 720x480 -channel 2 -i
/dev/video0 -acodec opus -b:a 32k -ac 1 -b:v 275k -vcodec theora -r 10
-map 0 -map 1 -vf lutyuv='y=gammaval(0.55)' -f segment -segment_time 180
-segment_list_size 999999999 -segment_wrap 999999999 -segment_list
segmentList.txt -reset_timestamps 1 videoSegment-%d.ogg
ffmpeg version: HEAD from a few weeks back. I can confirm that the above
command does NOT segfault when using ffmpeg commit
1de8a4f7366540df307841b2688dd361c0e32a06
configuration: --enable-libmp3lame --enable-shared --disable-htmlpages
--disable-podpages --enable-libopus --enable-libtheora --enable-libv4l2
}}}
AMD64 Debian Wheezy Xfce. All the dependencies to compile ffmpeg using the
above configure flags were installed using apt-get with wheezy as the
target.
