3.4.0 vs 3.3.3

[Shelly Adhikari <shelly at interrasystems dot com>]

Hello Guys,

Should I file a bug against gcc 3.4.0, the following compiles fine with 
gcc 3.3.3 but gives errors with gcc 3.4.0.

---------------------------------------------------------------------------------------------------------------------------

template <class A> class C;

template <class A> class B {
public:
   B() { }
   ~B() { }
protected:
   int abc;
   void g() {}
   friend void C<A>::f(B<A>* p);
};

template <class A> class C : public B<A> {
public:
   void f(B<A>* p) {
       p->g();
       int m = p->abc;
   }
};

int main() {
   B<int>*    y = new B<int>();
   C<int>    x;
   x.f(y);
}
