[zeromq-dev] Send&Receive is broken in v2.1.5?

[Pieter Hintjens]

Artem,

Thanks for identifying this error. I'm assuming it's a bug in some new
code that checks zmq_msg_t's for validity. The error is in libzmq
master, and was pushed downstream to the 2.1 branch without sufficient
checking. Mea maxima culpa.

I'm making a new 2.1.5 release now with your patch, which indeed fixes
the tests.
