I think your problem is the misunderstanding of the shared_ptr. The
shared_ptr is a class that _wraps_ another pointer (whether valid or not)
and keeps a reference count to how many other variables are using the
pointer. The following line:
if (rx)
is only testing if the wrapper is valid, NOT the actual pointer itself that
is being wrapped. What you really want is:
If (rx.get() != NULL)
