I think it would be a good idea to print the errno value before
asserting. Not knowing exactly where 0MQ prints messages, something like
this:

  if (err != ECONNREFUSED &&
      err != ETIMEDOUT &&
      ...
      err != ECONNABORTED) {
    fprintf(stderr, "Unexpected network error %d, aborting\n", errno);
    zmq_assert (false);
  }
