[zeromq-dev] Infinite loop while creating udp socket with invalid url

Hi all,

Just for some more exposure I need some feedback on an error I'm running 
into with dgram sockets.

Issue here: https://github.com/zeromq/libzmq/issues/4504

Basically an url with a port <1024 doesn't return an error (permission 
denied) but results in a infinite loop trying to create the socket in 
the IO thread.

This doesn't happen with a TCP socket.

I traced it down to the getsockopt call not retrieving any error while 
errno is 13.

Anybody experience with this?
