[zeromq-dev] Assert when sending from a polled REQ to a XREP socket.

[Pieter Hintjens]

Hi Delaney,

So, if 0MQ asserts or crashes when passed an invalid message on the
wire, we consider this a bug.  Since you have a nice test case, could
you report this to the 0MQ issue tracker, and post your code to a gist
(gits.github.com)?
