Bug: Failure to compile legal code (gcc-2.95.2)

[Mike Harrold <mharrold at cas dot org>]

Hi,

The code below fails to compile. However, if the commented line in class B
is uncommented, it compiles fine. I assume this is a bug, or I am missing
something very obvious.

Regards,

/Mike

class A
{
public:

  virtual A& operator<<(const char*);
  virtual A& operator<<(int);
};

class B : public A
{
public:

  virtual A& operator<<(int);
  //virtual A& operator<<(const char* x) { return A::operator<<(x); }
};

class C : public B
{
};

class D : public C
{
};


void fooA(A& x)
{
  x << "Hello";
}

void fooB(B& x)
{
  x << "Hello";
}

void fooC(C& x)
{
  x << "Hello";
}

void fooD(D& x)
{
  x << "Hello";
}
