Have a test case, and it's clear that any socket doing FQ input (pull
or dealer/xreq or sub) that leaves a part in the queue at close time
will cause the crash.

I've put the test case in the issues repo
(https://github.com/zeromq/issues), and have also added code to czmq
that flushes a socket before closing, which does solve the issue for
czmq applications:

            while (zsockopt_rcvmore (socket)) {
                zframe_t *frame = zframe_recv (socket);
                zframe_destroy (&frame);
            }

Not sure if it afffects 3.0 yet, but will make that test case when I
have a moment.
