Why would getnameinfo(NI_NUMERICHOST) fail here?  The code in
ikev2_msg.c is:

--8<--
        log_info("%s: %s %s from %s to %s msgid %u, %ld bytes%s", __func__,
            print_map(exchange, ikev2_exchange_map),
            (flags & IKEV2_FLAG_RESPONSE) ? "response" : "request",
            print_host((struct sockaddr *)&msg->msg_local, NULL, 0),
            print_host((struct sockaddr *)&msg->msg_peer, NULL, 0),
            betoh32(hdr->ike_msgid),
            ibuf_length(buf), isnatt ? ", NAT-T" : "");
-->8--

Maybe msg->msg_local is corrupt?
