Let me confirm one thing.
Did you also see a message "panic: bogus refcnt 0", in your panic?


As far as I investigated, only IF_CLONE_REMREF_LOCKED() can display
this message.  But it's called only in
if_clone_create/detach/destory(), and none of them seems to be called
according to the description in the PR.  (rtexpunge() in route.c also
has this message, but it is commented out by "if 0", so it is not the
cause of this message)

Thanks,
