Comment (by dtzWill):

 Ah, the code has changed.

 Re-running with latest git (commit
 d5d29ae3b0375320a7a34f85a5a90e8362550dbb) gives this new location:

 libavcodec/mpegvideo.c:3049:47: runtime error: pointer index expression
 with base 0x000000000000 overflowed to 0xfffffffffffffff0

 Attaching patch that reports the issue to help reproduce the issue.
