Hello

Does not crash to me. Could you get core dump (running bird with ulimit
-c unlimited) and send it to me? Do you use precompiled BIRD binaries
from some package?

This is just a terminology detail - it means for basic AF (i.e. IPv6)
default is 0, for OSPFv3-AF extended AFs (e.g. IPv4) default are values
from RFC 5838 (e.g. 64).
