Segfault while libaom-av1 2 pass encoding

[oloke]

Summary of the bug:

Hello, I was trying to encode some videos into AV1 with libaom. Most of them encoded fine, but 4 out of 11 I tried, were constantly segfaulting. I also tried encoding the same videos with libvpx-vp9, and there was no issue. I reproduced the segfault using ffmpeg version n5.0 from Arch Linux repos and static build from johnvansickle.

I recompiled ffmpeg as well as libaom in debug mode using ​FFmpeg-Builds and ran ffmpeg with gdb.
Now I'm not getting segfaults, just libaom assertion error.

I picked one video out of few that were crashing.
The first pass doesn't have any problems and exits with status code 0. The second one always crashes near the end of encoding. The video itself is 3840x2160 @30fps h264 yuvj420p, 1923 frames long, recorded using Oneplus phone.
The libaom version I used is the latest git (​f78cf964666570438a022e6e67e597073a39ed62). If that's libaom bug, sorry for reporting in the wrong place.

I'm attaching the full report file as well as the shortened list of commands I ran.
