slicing problem

代码

class Base{public:    Base():m(0){};    //Base(const Base& rhs):m(rhs.m){cout<<"Copy constructor, rhs is "<<&rhs<<" this pointer is "<<this<<endl;}    void add(){m++;};    int m;};class Derived : public Base{};int main(){    Derived d;    cout<<d.m<<endl;    static_cast<Base&>(d).add();    cout<<d.m<<endl;    //so called "slicing problem"    static_cast<Base>(d).add(); 　 //Base(static_cast<Base&>(d)).add();    cout<<d.m<<endl;    return 0;}

嘿嘿，猜猜看static_cast<Base>(d).add(); 这一行，编译器到底干了些什么.
