You forgot the typeid check that your original code had.

I wasn't precise in my reply. You had written:

    if ( typeid(*p) == typeid(MostDerived) ) pd = p + offset;
    else if ( typeid(*p) == typeid(MostDerived2) ) pd = p + offset2;
    else if ( typeid(*p) == typeid(MostDerived3) ) pd = p + offset3;
    else pd = dynamic_cast<Derived*>(p);

I had meant you can use static_cast in the case of the pointer arithmetic you
had there, not the whole thing.
