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);
}
