	named dies as follows:

	Aug  4 10:47:32 abstr named[11539]: /home/builds/ab/netbsd-5/src/dist/bind/lib/dns/rdata.c:399: REQUIRE(((rdata)->data == ((void *)0) && (rdata)->length == 0 && (rdata)->rdclass == 0 && (rdata)->type == 0 && (rdata)->flags == 0 && !((void *)(((rdata))->link.prev) != (void *)(-1)))) failed
	Aug  4 10:47:32 abstr named[11539]: exiting (due to assertion failure)
	Aug  4 10:47:32 abstr /netbsd: pid 11539 (named), uid 14: exited on signal 6 (core not dumped, err = 1)

	It should not ever exit as a result of any data from the network.
