[zeromq-dev] pure virtual function call in select.cpp

[Hamster]

Hello!

If any of you ever met "pure virtual function call" in zmq::select_t::loop() ?
The disposition is like following: W2008/x64, zmq 2.1.7 and 2.1.10 (both do the
same thing), server application implementing ZMQ_XREP socket at certain
conditions ends up with the above mentioned error. (sh)it happens time to time
while clients do multiple zmq_connect, zmq_send, zmq_poll/zmq_recv, zmq_close
sequences (unsuccessful logon scenario). Server (in the main thread) do
zmq_bind, zmq_poll/zmq_recv on two sockets, one is networked ZMQ_XREP where
clients are connected and another is ZMQ_UPSTREAM where threads put their
responses after processing network requests (then main thread do zmq_send).

The stack is quite short: thread_routine() and then zmq::select_t::loop(), the
line is:

                fds [i].events->in_event ();

I suppose that this is kind of race condition, but can not isolate it well right
now. Do you have any thoughts?
