I did add Jira issue comment before posting to mailing list. https://zeromq.jira.com/browse/LIBZMQ-304. 

I think others have seen this bug too. This mail from Michael is very highly the same bug:

> Hi,
> I am trying to do explicit message routing using Router/Dealer
> connection pattern, as documented in the zguide:
> http://zguide.zeromq.org/page:all#toc49 
> But the messages never arrive at the destination.
> Please find the code here:

> Program output here:

> Cheers,

I tested Michael's code in 2.1.11 and got output:
Sending Routing msg
Sending Payload
Waiting for payload
Payload recved

In 3.1 it hangs forever in 'zmq_recv (dealer, &msg, 0);'.
