Description llyyr 2023-08-16 10:28:56 UTC 
This is an upstream issue that causes worse than quadratic performance regressions for code that uses posix_memalign, which includes any ffmpeg-based apps and various others such as some parts of Mesa.

The issue has been fixed upstream already with two new commits that haven't yet been released yet.
