If we use smart proxy, the following narrow function call
will return a pointer to the created smart proxy object.

        TestSmart_var phello = TestSmart::_narrow(obj);

However the returned object is a local object with is_local_ = true.
When phello out of scope, it will go ahead invoking :

CORBA::Object::_remove_ref (void)
{
if (this->is_local_)
return;
...
}

Since is_local_ is true, it is just returned and never deleted, that's
why the destructor of the smart proxy was not invoked.

If we let the smart proxy class  inherit from
TAO_Local_RefCounted_Object, then the proxy object will have the correct
reference count and get deleted as expected. See the diff below.

Also this will fix the problem of getting crash when calling _non_existent()
with smart proxies.

I provided a test based on the two problems. The test is now in
$TAO_ROOT/tests/Smart_Proxies/dtor.
