Question on dynamic binding

Hi,

I've following code :

class Base {
public:
    virtual void func() { std::cout << "Base" << std::endl; }
};

class Derived : public Base {
public:
    void func() { std::cout << "Derived" << std::endl; }
};

class MostDerived : public Derived {
public:
    void func() { std::cout << "MostDerived" << std::endl; }
};

int main(int argc, char **argv)
{
    Base *pBase = 0;
    Derived *pDerived = 0;
    try {
        pBase = new MostDerived;
        pDerived = new MostDerived;

        if (pBase) {
            pBase->func();
            delete pBase;
            pBase = 0;
        }
        if (pDerived) {
            pDerived->func();
            delete pDerived;
            pDerived = 0;
        }
    } catch (...) {
        if (pBase) delete pBase;
        if (pDerived) delete pDerived;
    }
    return 0;
}

On execution, why the o/p is
MostDerived
MostDerived

I's expecting it to be

Derived
Derived

as after Derived, it's no longer virtual ... Please clarify me the
reasons ...

I've verified it with g++ and Sun compiler ... same behavior with both
the compiler ...
