It is CURRENT, you can see revision for each dump in core.txt.
I don't think this problem was fixed. I suspect the problem occurs when tun(4)
interfaces are going down. There are two sorts of panic, one is in
nd6_dad_timer(), second is in route_output(). It seems in both cases ifnet
pointer is already freed.
