BIRD 3.2.1 - abort/core dump on startup on FreeBSD 15.

[David Petera]

Hi Robert,

thanks for the report.

How did you manage to fix the BGP issue? From what you sent us it should 
be working (we use two channels per BGP protocol in our tests as well), 
so I am curious.

Would you be able to sent us logs just before the crash, config, core 
and exact binary you used? So we have a better idea what we dealing with.

Thanks,
David
