The program shouldn't definitely cause a segmentation fault. I'll have a 
look at it.

However, I am not sure what you are trying to do. If you want to send a 
request and receive reply, do it this way:

zmq::message_t request;
... fill it in...
s.send (request);
zmq::message_t reply;
s.recv (&reply);
... process the reply ...
