Odd function resolution

[helios]

Given:

class A{
public:
    Foo foo() const;
    virtual void foo(Foo &) const = 0;
};

class B : public A{
public:
    void foo(Foo &) const;
};

//...

B *b = /*...*/;
b->foo();
((A *)b)->foo();

Why does MSVC 12 complain about foo() not taking 0 arguments for the first call, but accepts the second one?

There is no inheritance in your example, you are converting a pointer to an unrelated type and thus getting undefined behavior.

Sorry, fixed it.

Name hiding.

I see. Thanks.
