#7557: crash when overlaying image partially-offscreen

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
