Process hangs and won't exit correctly when sending incorrect message from DEALER->REP

[Madd0g]

I have the same DEALER code sending messages to REP/ROUTER, the only difference that sending to REP requires an extra .send() in front of the actual message.

let socket = zmq.socket('dealer');
socket.bindSync('tcp://127.0.0.1:5555');
....
if (isRep) {
    socket.send('', zmq.ZMQ_SNDMORE);
}
socket.send(envelope);

Right now if I forget to pass isRep the message is not received, but the process also hangs after CTRL+C and I have to kill it with kill -9.

Anything I can do to catch this error and prevent it? This seems like such an easy mistake to make, I keep forgetting to pass the isRep.

Thanks

Recently we have released 6.0 beta. It features a new API that addresses some fundamental issues with the previous API and also addresses a number of stability bugs. To make upgrading easier it includes a compatibility layer with versions 4.x/5.x. It would be great if you could give the latest version a spin to see if this solves this particular issue. If you run into any problems with it, feel free to report it here or in a new issue.
