I don't think it is possible to have multiple sockets bind to the same endpoint. Are you certain that the result code from calling bind is 0? If it is, then this is likely a bug and should be reported (with sample code).

Alternately, if you are running this on Windows then I don't think inproc or ipc transports are supported on that platform. That should also error out (if you are on Windows).
