Summary of the bug:
Trying to create an MKV video by looping a PNG for a specified amount of
time leads to a segmentation fault.
How to reproduce:

The full log generated using FFREPORT=1 while debugging with GDB (see
below) has 27000 lines, so I'll put it in an attachment.
`black.png` was generated using ImageMagick `convert -size 2x2 xc:black
black.png`, but I'll also attach it.
The crash doesn't always happen at the same time, sometimes it's basically
instant, sometimes only after an hour of video has been encoded. It seems
to happen more often if the encoding speed is higher.
