zmq_send() & zmq_recv() - "Bad address" error and MetaTrader crash

[Wojtekcdv]

Hi!
I created a simple client in mql4 to communicate with my java program on port 5555.
0MQ_client.txt
Unfortunately zmq_send() & zmq_recv() return "-1" and zmq_errno() for both of them returns 14, which corresponds to "Bad address" error message.
Could you tell me what might be the problem?

Essential informations:

• Windows 10 64 bit
• MetaTrader version 4.00 build 1065 installed from FOREX.com
• OTMql4Zmq from git

Thank you in advance!
