A destructor isn't called in the test case below (works with gcc 4.2.1 and
MSVC2010).

#include <iostream>

using namespace std;

template<typename T> class Handle {
public:

    Handle() { cout << "Handle::Handle()" << endl; }

    Handle(const Handle& r) { cout << "Handle::Handle(Handle&)" << endl; }

    ~Handle() { cout << "Handle::~Handle()" << endl; }
};

class P {
public:
    Handle<int> h;

    Handle<int> getHandle() {
        return h;
    }

    template<class T> void 
    f(Handle<T>& h) {
        h = getHandle();
    }
};

int
main(int, char**) {
    P p;
    Handle<int> h;
    p.f(h);
}
