	Well line 124 is the REQUIRE below.

isc_boolean_t
dns_rdataset_isassociated(dns_rdataset_t *rdataset) {
        /*
         * Is 'rdataset' associated?
         */

        REQUIRE(DNS_RDATASET_VALID(rdataset));

        if (rdataset->methods != NULL)
                return (ISC_TRUE);

        return (ISC_FALSE);
}

	Now there are 159 calls to dns_rdataset_isassociated().

grep -r dns_rdataset_isassociated lib bin/named contrib/dlz | grep c: | wc
     159     493   10529

	Without a stack backtrace no one has a hope of working
	out where things went wrong.

	Mark
