        src/sys/external/bsd/ipf/netinet: ip_dstlist.c

Log Message:
PR/47270: Paul Goyette: ipftest -N aborts
1. check for NULL before de-refencing; in particular sel is assigned to NULL,
   in the default case, and then couple of lines down we do sel->
2. gcc appears to optimize u_32_t hash[4], to u_32_t hash, since we only
   use hash[0], disregarding the fact that we pass it to MD5Final() leading
   to stack corruption. Use an explicit union, so that the compiler stops
   butting its head where it shouldn't.
