I have developed my own patch that appears to solve the problem. In file udp.c, line 216, replace
ip_addr_cmp(&(pcb->local_ip), &(iphdr->dest)))) {
with
ip_addr_cmp(&(pcb->local_ip), &(iphdr->dest))) ||
ip_addr_isbroadcast(&iphdr->dest, inp) ) {
effectively adding a check for broadcast to one of the many checks of the packet control block. I am not sure this is rigorously correct, but appears to work. Comments invited.
Regards,
Tim

Tim, please join the lwip-users mailing list and submit the problem and your proposed solution. Development on lwIP is active as a new major upgrade is in the works. You didn't mention lwIP version and you'll need to do this there. Here would have been nice too. :)
