Description

PMR 02310,K78,000

The well-formed program below fails to compile with XLC++ 8.0 on AIX (I haven't checked Linux). It compiles successfully with XLC++ 7.0.

$ cat t.cpp && xlC -qversion && xlC -c t.cpp

template <class>
struct A {
static int foo ();
static int bar (int);
};

template <class, class> class B;

template <class T, class U>
struct C {
int operator*()

{ return U::bar (b->baz ()); }

B<T, U> *b;
};

template <class, class U>
struct D {
void barf (U);
};

template struct D<int, C<int, A<int> > >;

template <class, class U>
struct B {
int baz ();

virtual int foobar (int i = U::foo ())

{ return i; }

};

template <class T, class U>
void D<T, U>::barf (U u)
{
*u;
}
