Dear BIRD users,

we are releasing BIRD versions 3.2.0 and 2.18.

Hi,

After upgrading our route servers from bird-3.1.5-1.el9.x86_64 to bird-3.2.0-1.el9.x86_64 (Fedora EPEL RPM packages), BIRD crashes shortly after startup with the following output (with "log stderr all"):

[tore@rs1-osl3 ~]$ sudo bird -f -u bird -g bird
bird: 2026-01-05 10:02:16.298 [0001] <WARN> /etc/bird.conf:47:62: Missing 
authentication option, assuming MD5
(above warning repeated for several other lines in the config file, this was 
also warned about in BIRD 3.1.5 though)
bird: 2026-01-05 10:02:16.298 [0001] <INFO> Started
bird: 2026-01-05 10:02:16.320 [0001] <BUG> Assertion 
'DG_IS_LOCKED(orig->domain)' failed at lib/resource.c:208
Aborted

This appears to be triggered remotely. If I block all incoming BGP connections in the firewall before starting BIRD, it starts runs fine - until I remove the block, at which point an RS client connects and BIRD crashes.

I cannot share the configuration file in a public forum like this mailing list, but would be happy to send it (or any other debugging information that might help) directly to the developers.

Tore
