gcc 2.95.1 fails to compile correct code

[Andrew Fitzgibbon]

EGCS 1.1.1 compiles this, I'm pretty sure it's correct.

The compiler errors rather than producing an object.



g++ -v -xc++ - << EOF
template <class T> struct A;

template <class T> A<T> operator- (const T, const A<T>&);

template <class T> struct A {
  A<T> operator- (const A<T>& ) const;
   
  friend A<T> operator- <> (const T, const A<T>&);
};


template <class T>
struct IUE_matrix {
  void inplace_transpose() {
    A<int> move;
  }
};

EOF
