I've reconfigured my setup now so I can get usable core dumps. Let's
hope bird crashes again soon.

I ran into a third crash yesterday (opcode 56776) but I
haven't been able to reproduce them reliably. What the all have
in common is that they always occured after I changed a filter function
and called birdc configure.
