--- Comment #4 from Edward Tomasz Napierala <trasz@FreeBSD.org> ---
This is still happening with yesterday's CURRENT.

It looks like the bug is caused by rtnl_handle_getroute() being called with
family=255, which then causes assertion in rt_tables_get_rnh_ptr().  I'm not
sure where this value - which from I assume came from userspace - should be
handled?

I've pinged glebius@, he's done some Netlink work recently.
