Bug,Exclusive always true!

[tms2003]

when I try use this code:

channel->DeclareQueue(this->_rmq_queque, false, true, false, false);

The queque's exclusive be true always!
but,I get this declare:

Channel::DeclareQueue(const std::string &queue_name, bool passive,
                                  bool durable, bool exclusive,
                                  bool auto_delete)

so, what ever i set(true or false),the exclusive always true!
