Major Description
A receiver attaches to the router on a link routed address which is serviced by the standalone router via a route-container connection connected to the broker.
When the receiver and the broker send detaches at the same time, the receiver side pn_link gets freed and the router tries to forward the detach received from the broker on to this freed pn_link and crashes.
