Hello, I am here to report a crash encountered upon reconfiguration of bird. The crash is reproducible using the `birdc reconfigure soft` command. In this example I changed the OSPF link type (from pointopoint to broadcast). However, I have seen the crash with other reconfigurations as well. Below I entering the configurations, log and stack trace. This hopefully helps in debugging the issue. If more information is needed, let me know. I am happy to help where I can. The tested version is v3.1.4. ``` # bird -u bird -g bird -c /opt//bird/bird.conf -d bird: 2025-10-28 12:37:48.107 [0001] Chosen router ID 10.89.112.123 according to interface enp6s0 bird: 2025-10-28 12:37:48.107 [0001] Started bird: 2025-10-28 12:37:50.621 [0001] Reconfiguring bird: 2025-10-28 12:37:50.621 [0001] Adding protocol ospf1 bird: 2025-10-28 12:37:50.621 [0001] Reconfigured bird: 2025-10-28 12:37:53.885 [0001] Reconfiguring bird: 2025-10-28 12:37:53.886 [0001] ospf1: Restarting interface enp11s0.3676 (172.21.8.0/28) in area 0.0.0.1 bird: 2025-10-28 12:37:53.886 [0001] Trying to lock in a bad order: 00007ffed0528670 00007f9a66c1a3b8 Aborted (core dumped) ``` ``` # birdc 'configure soft "/tmp/ospf/ospf-2.conf"' BIRD 3.1.4 ready.
