It should just fail fast. If the unthinkable happens (zmq_msg_init fails), then the program should come down. It's clearly a *bug* somewhere, so the author should fix it.

Your philosophy may be different, but the fail-fast philosophy has worked pretty well for 0mq (grep the source base for "assert").
