[zeromq-dev] Bad Pointer Exception with ZMQ 2.2.X

[Viviano, Aaron]

Hello ZMQ Devs,
I found the issue and it is with CLRZMQ and not LIBZMQ. Turns out that CLRZMQ was using the same object for both sending and receiving. When sending messages at a high enough rate of speed CLRZMQ was deleting the message at the same time that LIBZMQ was using it.

For those curious the issue is with "private IntPtr _msg;" in Socket.cs. Remove that variable and put unique instances in the send, forward, and receive functions that previously used the _msg variable.

My apologies for not finding that the flaw was outside LIBZMQ earlier. I will contact the CLRZMQ Devs about this.

Thank you,
Aaron Viviano
