Question

I can’t get ZeroMQ C++ wrapper to receive multipart messages. The same code using C version works just fine, but it leads to an exception with no explanations at all with C++. The multipart handling code is as follows:

int _tmain(int argc, _TCHAR* argv[])
{
    zmq::context_t context(1);
    zmq::socket_t socket(context, ZMQ_REP);
    socket.bind("tcp://*:5555");

    while(true) {
        // the following two lines lead to exception
        zmq::message_t request;
        socket.recv(&request);

        //zmq_msg_t message;
        //zmq_msg_init (&message);
        //zmq_recv (socket, &message, 0);   
    }

    return 0;
}

It is extremely simple; this version does not work. but if I comment out the first two lines in the while loop and uncomment the currently commented (C version) code, it works.
This is Windows XP sp3, Zeromq 2.1.1 and Visual Studio 2010 Express.

If I send single part messages, both versions work fine.
What am I doing wrong?

I decided to use the C version of the code. In general all examples seem to be in C anyway.
