I'm not seeing any error messages when starting up the broker in daemon mode. E.g. if the port is already in use, the data directory does not exist or whatver, no error message is printed but the broker does not start.
This seems to be caused by -r649294 (I suspect the changes to Daemon.cpp): http://svn.apache.org/viewvc/incubator/qpid/trunk/qpid/cpp/src/qpid/broker/Daemon.cpp?r1=649294&r2=649293&pathrev=649294
