aom_image.c in libaom in AOMedia before 2021-04-07 frees memory that is not located on the heap.
Created aom tracking bugs for this issue:
Affects: epel-all [bug 1961377]
Affects: fedora-all [bug 1961376]
I'm in the process of updating AOM to version 3.1.1, when it is released.
I am also considering waiting for libjxl to be packaged and for its dependency highway to have its remaining bugs fixed (hopefully within the next two weeks).
libjxl provides the tune=butteraugli function.
