Description

Running the system_tests_edge_router under valgrind:

Appears that the endpoint allocated here in addr_proxy.c:

//
// Attach a receiving link for edge address tracking updates.
//
ap->tracking_endpoint =
qdrc_endpoint_create_link_CT(ap->core, conn, QD_INCOMING,
qdr_terminus_normal(QD_TERMINUS_EDGE_ADDRESS_TRACKING),
qdr_terminus(0), &ap->endpoint_descriptor, ap);

is not released when the router is shutdown
