Hi.
We use bird as routing daemon on our linux routers.
At now we have one ospf and 7 bgp protocols in configuration.
During last bgp reconfiguration ( we play with med attribute) segfault
occurred.
I see this in gdb:
Program terminated with signal 11, Segmentation fault.

We cant reproduce this segfault but we have coredump. BIRD version 1.3.9
from debian packages(bird_1.3.9-1_amd64.deb)
