[zeromq-dev] zmq_ctx_destroy() stocks forever when statically built on Windows

Hi Folks,

I built ZeroMQ 3.2.2 on windows both static and dynamic release/debug
versions.
I use the C++ wrapper (zmq.hpp) from Github.
Both my client and server are running on the same machine (Windows 7) and I
built them with MSVC++ 10.
The dynamic version of the library works just fine for both client and
server.

But I have to use the static version for one of my clients because it's a
game written on top of UDK.
We use the native code using this method:
http://udn.epicgames.com/Three/DLLBind.html
And we have built all libraries statically with our code because of the
limitations.

Now the problem is, whenever we want to close the context the game won't
exit and it stocks forever.
I thought maybe it's a bug in the C++ wrapper of ZeroMQ
then I decided to use the C bindings directly.

This is piece of our code:

Since it's unsafe to delete void* pointers is there any way to stop the
context which doesn't respect ZMQ_LINGERE.
Even simple code like this won't exit gracefully (no connect, no message):
http://pastebin.com/KbyvHCr9

But this one exits cleanly, which of course it's useless:

It's worth noting that I have just one socket in my app. And this code
works In my testbed which links dynamically.
Of course the static version works just fine, but the only glitch is the
exiting part. The game stocks forever at
rc = zmq_ctx_destroy(m_context); and the CPU usage varies between 25-50%.

And this is my log from building ZeroMQ statically for UDK dll-binding:

Thanks in Advance,
