Although the note about stack is technically correct, the behaviour is undefined from C programming language standpoint. I think it must be clearly stated the lifetime of the data must be controlled. In fact it must be kept until zeromq context closed, isn't it?
In zguide the zmq_msg_init_data syntax with zero ffn is used a couple of times, though I failed to find if it is explained why it is wrong or at least dangerous.
