I don't know!
I just wanted to point out that so far, the "bugs" that were 
worked-around in FFmpeg 3.1.1 were bugs in other applications.

I still do not understand completely: Is the crash still reproducible 
after recompiling Kodi or not?

I don't know but...

... adding a backtrace should work fast, no?
If another developer looks at the backtrace, he might know what the 
issue is.

Bisecting FFmpeg takes less than 20 minutes here, I know it would take 
you longer but if the backtrace does not help, this is the only way to 
find out what the issue is.
I can try helping to create a specific configure line to speed up the 
backtrace.
