Note that this is in 5.3-CURRENT, and leading up to this there was a route
flush and a "route add 128.8.244.0/24 128.8.244.1", then I got this
when I did "ping 128.8.244.1."  The line in question, with some context,
is:

                        lookup:
                                RT_UNLOCK(rt0);
                                rt = rtalloc1(rt->rt_gateway, 1, 0UL);
                                RT_LOCK(rt0);
                                rt0->rt_gwroute = rt;

Backtrace went, syscall sendto sendit kern_sendit sosend rip_send rip_output
