 Summary of the bug:
 What you were trying to accomplish: a vertical wipe effect by overlaying
 an image on to a video with a y-expression based on the current frame. The
 command line pasted below doesn't bother with the expression, just to
 simplify things but it does still crash.

 Note: I'm running this on CoreOS

 How to reproduce:
 {{{
 ffmpeg -i pig.jpg -i tooth.mp4 -filter_complex
 "[1:v][0:v]overlay=x=5:y=-5" output.mov
