Hi George,

We don't have HP-UX here so it would be helpful if you can check 
following changes and let us know whether they help to get rid of the

Copying the memory explicitly may help here:

memcpy (addr_, res->ai_addr, sizeof (sockaddr_in));

I would say the compiler doesn't recognise "assert (false)" as a 
termination statement. Try this:

     assert (false);
     return false;

Is there a different way to convert hostname to IP address on HP-UX? If 
so, the code may be placed here with #ifdef ZMQ_HAVE_HPUX...
