Hmmm. Does it help if you delete this code block?

        if (SERVER_PORT == 67 && CLIENT_PORT == 68) {
                /* Use only if standard ports are in use */
                /* Ignoring error (kernel may lack support for this) */
                if (setsockopt(fd, SOL_SOCKET, SO_ATTACH_FILTER, &filter_prog,
                                sizeof(filter_prog)) >= 0)
                        DEBUG("attached filter to raw socket fd %d", fd);
        }

Can you collect "tcpdump -nlieth0 -s0 -vvv -xX port 67 or port 68" output
for both?
