Thanks a lot, this actually fixed my problem.

In case it may help someone else: I also need to make the socket
reusable by

 setsockopt(tcp_broadcast_receiver, SOL_SOCKET, SO_REUSEADDR, &on, sizeof(on)

and I have found that this, contrary to the IP_ADD_MEMBERSHIP case,
must be called BEFORE I bind the socket!

Thanks again!
