[Bug c++/13937] New: virtual method hides overloaded method in base class

[msieweke at broadcom dot com]

// Just any old forward declaration. 
class Thingy;

// Base class A stores a pointer to an object of type Thingy, and provides
// accessors to set and get the pointer.
class A
{
public:

    A(void) {}
    virtual ~A() {}

public:

    virtual void Value(Thingy *pThingy);
    Thingy *Value(void) {return pfMyThingy;}

private:

    Thingy *pfMyThingy;
};


// Derived class B overrides the accessor method in the base class so that it
// can do something special when a Thingy is being set.
class B : public A
{
public:

    B(void) {}
    virtual ~B() {}

public:

    virtual void Value(Thingy *pThingy);
};



// This function tries to get hold of the Thingy object, which should resolve
// to A::Value(void); however, the compiler seems unable to make this
// connection.
void MyFunction(void)
{
    B *pMyB = new B;
    Thingy *pThingy;

    pThingy = pMyB->Value();
}

/*

This is the error produced by the above code:

../bug.cpp: In function `void MyFunction()':
../bug.cpp:48: no matching function for call to `B::Value()'
../bug.cpp:35: candidates are: virtual void B::Value(Thingy*)


If we change the code to:

    pThingy = ((A *) pMyB)->Value();

it will compile without complaint.

// NOTE: This may be related to bug #13590
// Bug duplicated with G++ 3.3.2 and 3.2.1
