FFmpeg crash when recording desktop

I'm using x264-git and ffmpeg-svn from AUR.  I am attempting to record usage of xcalc as an example of using FFmpeg to capture a specific application on the desktop.   However, FFmpeg will always crash at certain resolutions, but it will encode if I change the resolution from -s 228x332 to -s 232x332.  I asked at #ffmpeg and nobody was able to replicate this.  My system is i686.

Can anyone confirm this behavior?

FFmpeg command that crashes:

ffmpeg -r 30 -s 228x332 -f x11grab -i :0.0+0,0 -g 300 -threads 0 -vcodec libx264 -vpre fastfirstpass -vpre baseline -sc_threshold -1 -cqp 22 -flags -loop -y x11grab.mp4

FFmpeg output:
