问在抽象基类上使用__declspec(novtable)会以任何方式影响RTTI吗？

EN

struct __declspec(novtable) B {
    virtual void f() = 0;
};
struct D1 : B {
    D1() {
    }       // after the construction of D1, vptr will be set to vtbl of D1.
};
D1 d1;      // after d has been fully constructed, vptr is correct.
B& b = d1;  // so virtual functions and RTTI will work.
b.f();      // calls D1::f();
assert( dynamic_cast<D1*>(&b) );
assert( typeid(b) == typeid(D1) );

struct D2 : B {


    D2() {  // when enter the constructor of D2 \  
            //     the vtpr must be set to vptr of B \
            //     if  B didn't use __declspec(novtable).
            // virtual functions and RTTI will also work.

            this->f(); // should calls B::f();
            assert( typeid(*this) == typeid(B) );
            assert( !dynamic_cast<D2*>(this) );
            assert( dynamic_cast<B*>(this) );

            // but __declspec(novtable) will stop the compiler \
            //    from generating code to initialize the vptr.
            // so the code above will crash because of uninitialized vptr.
    }
};

struct D3 : B {  // ISO C++ semantic
    D3() {       // vptr must be set to vtbl of B before enter
    }            // vptr must be set to vtbl of D2 after leave
};
