I have a couple of openvpn tunnels between two test machines and I was bringing
the tunnels up and down with a second of delay and noticed that ospfd started
segfaulting. I removed "ip ospf network non-broadcast" I had added to one of the
tunnels to stop some redundant log messages and it did not crash any longer.
Program received signal SIGSEGV, Segmentation fault.

okay, it seems that for this to work, my hack of a interface naming script has
to be in place.
I have a script that takes the newly created openvpn tunnel device, brings it
down, renames it, brings it up, drops it's address and re-adds it (the latter
two were to work around a zebra bug of a sort).
i tried to bring the link up and down rapidly, but it didn't produce the segfault.
