[zeromq-dev] ZMQ 2.0.6 connect SUB socket error

[Matthew Giedt]

Hello --

I just upgraded from 2.0b2 to 2.0.6 -- (downloaded, ./configure --> make -->
make install, verified new libraries and include)

When running the following program with:

./test tcp://lo:5551 tcp://localhost:5551 data.txt

 I get:

publishing on: tcp://lo:5551 success.
subscribing on: tcp://localhost:5551
terminate called after throwing instance of zmq::error_t
  what():  Invalid argument
Aborted

Are you guys seeing the same thing? Is it an upgrade from previous beta
issue?

With thanks,
-Matt

            const char* xml = line.c_str();

            msg.rebuild ( len );
            memcpy( msg.data(), xml, len );

            pub.send( msg );
            sub.recv( &msg );

            cout << " --> " << (char *)msg.data() << endl;

            sleep( 1 );
        }

    xmlfile.close();
    return 0;
