third (?) bug in 3.0.0

[Marek Zarychta]

I tried BIRD 3 on FreeBSD, seems to build fine including both flavors: 
netlink and rtsock.

Only the netlink flavor was tested in runtime. In small, testing 
scenario with OSPF and BGP it seems to run fine. When deployed in 
production setup with dual-stack and 2x full-view the daemon crashes 
almost immediately  with SIGSEGV. It was non-debug built, so  cores will 
not be much useful, though I can share them.

Cheers
