Yes. The point is that you should pass socket _handle_ to zmq_poll 
rather than pointer to zmq_socket_t object. The handle can be retrieved 
by casting zmq_socket_t to void*:

socket_t s (ctx, ZMQ_P2P);
pollitem_t item;
item.socket = s;

So it's user error. The documentation was modfied to make it clear.
