Is it these lines which are the problem with c_str() in the Paranoid Pirate
Queue?
msg.push_front((char*)identity.c_str());
msg.wrap (it->identity.c_str(), NULL);
What can be done to fix the problem, not using uuid identifiers? Replacing
uuids in the Paranoid Pirate Queue code with calls to s_set_id ()?
But it begs the question; how should the uuid identifiers be properly
handled and passed around in code? Surely Paranoid Pirate pattern must have
worked with uuids at some point in time otherwise how would it have passed
muster for the zeromq guide?
Confused.

The zmsg class api takes in char* and the pirate queue has code that passes
it identities as c_str(). This doesn't work since identities are not nul
terminated c strings and may contain nuls.
It works for the workers only because they explicitly set their own id to
something containing only characters. See s_set_id ().
