Issues

zmq receives NULL message (not empty string) after the program gets HUP signal

In "tcp" model, zmq_assert(sessions.empty()) when close router socket.

Selecting/Polling read event (ZMQ_FD) on XREQ sometimes never returns

wsa_error_to_errno() calls abort() on WSAEACCES

poll-based zmq_poll crash with too long timeout

Incorrect reply routing for ZMQ_REP/ZMQ_XREP socket

Assertion fail for IPv4 Interface String

zmq 2.1 dosn't follow the ZMTP/1.0 spec.

Assertion: Assertion failed: ok (mailbox.cpp:79)

ZMQ uses system time for polling timeout

RuntimeError when calling zmq.Context on a computer with a firewall

Memory leak in certain instances at session.cpp:98

O_CLOEXEC flag used in ip.cpp:192 is supported only on Linux kernels 2.6.27+

Unexplained memory growth when passing message from a pull socket to a publish socket.

"E: unhandled error on recv: 11/Resource temporarily unavailable"

ZMQ_DEALER seems to be dropping messages even though HWM should be cause blocking

Potential bug with linger

Assert: No such file or directory rc != -1 (kqueue.cpp:76)

Windows build broken in 2.1, 2.2, 3.0

push/pull + HWM + slow puller + zmq_close = lost message
