Dear BIRD Developers,
I saw two BIRD crashes today. This happened when I was running birdc configure
with a change to the list of interfaces in a direct protocol.
I have the core dump files if they might be helpful.
Sep 29 21:57:59 hostname1 bird[8950]: Restarting protocol direct1

0).
Sep 29 21:58:07 hostname1 systemd-coredump[9766]: [🡕] Process 8950 (bird) of
user 980 dumped core.
