This one is in libc however it's called from glib2 code:

Comment 2 David Jaša 2023-10-17 12:11:01 UTC 
reassigning similarly as el8 issue: https://issues.redhat.com/browse/RHEL-13123
Comment 3 Michael Catanzaro 2023-10-17 13:44:57 UTC 
An upstream bug report would be good.

If you are able to reproduce the issue, then valgrind would be a sure way to debug this since it is memory corruption, but we'd probably need help from NetworkManager developers to figure out how to run it under valgrind.
Comment 4 David Jaša 2023-10-19 17:47:32 UTC 
Upstream issue is here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1403
Comment 5 Aoife Moloney 2024-02-15 22:59:20 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle.
Changing version to 40.
