I ran a dnf upgrade on a bunch of machines. The first one segfaulted in the cleanup phase. While I was pondering what to do about it, maybe a cosmic ray hit an unfortunate capacitor in one of the RAM sticks perhaps, another one splurted this out:
Transaction Summary

Total download size: 514 M
Is this ok [y/N]: y

corrupted double-linked list

A core dump showed this:

This strongly suggests a bone-fide bug. A rerun of 'dnf upgrade' succeeded without any fanfare.
I'm fully updated out, but perhaps someone who has a bunch of updates to install could run dnf upgrade under valgrind, and see what shakes out.
