Compile error when explicitly instantiating shared_ptr by jmcmod

Unable to use explicit instantiation on shared_ptr since upgrading to Visual Studio 2010.

I believe the problem exists in the routine below because _Mybase (which is _Ptr_base) does not have a swap method. It, instead, has a _Swap method.

    void swap(_Myt&& _Right)
        {    // exchange contents with movable _Right
        _Mybase::swap(_STD move(_Right));
        }

I removed the explicit instantiation and it resolved my problem.

Note that the problem can also manifest via the following (granted it would be a strange thing to do):
std::tr1::shared_ptr<int> a;
a.swap(std::tr1::shared_ptr<int>(new int(1)));
