Memory access violation in zmq.green (gevent) - How can I fix this?

I have a zmq client running and want to change to async calls to the corresponding server.

But when I import the gevent version import zmq.green as zmq, at some point I get a Process finished with exit code -1073741819 (0xC0000005), a memory access violation.

My question is: How can I fix this or is there another way to use zmq with gevent?

I am running:

• windows 10,
• pycharm (close to latest version),
• python 2.7.13
• pyzmq 17.0.0,
• zmq 17.0.0 0.0.0 (as reported, not sure)
