BIRD crashes on FreeBSD with ipa_zero()/ipa_is_ip4() assertion

Hi, I'm trying to switch a FreeBSD IXP router from another routing daemon to BIRD for BGP. I already have OSPF running on the same system, and BIRD works without any problems. However, after starting BIRD and establishing/attempting to establish BGP sessions, I get the following error multiple times in `bird.log`: [0001] <BUG> Assertion 'ipa_zero(s->saddr) || ipa_zero(s->daddr) || (ipa_is_ip4(s->saddr) == ipa_is_ip4(s->daddr))' failed at sysdep/unix/io.c:1767 Many seconds after these errors, BIRD crashes. BIRD version: 3.3.2 (the same issue also occurs with older versions) FreeBSD version: 16.0-CURRENT (same with 15.1-RELEASE) Thanks, -- Pouria
