Dear All,
I am unable to understand following test case behaviour.
When i compile and execute this with g++ 3.4.6 it works fine.
But when i compile and execute this with g++ 4.3.2 it aborts.
I think the test case is OK.
But g++ 4.3.2 having bug.
Below is test case:
==========================================================
#define ieq(X,Y) if((X)!=(Y)) abort();
extern void abort ();
struct B_
{
int i;
};
struct D_:public B_
{
};
D_ d_;
int f_ (B_ &)
{
return 100;
}
template < class T > int g_ (T t)
{
return f_ (d_) + f_ (t);
}
int f_ (D_ &)
{
return 1;
}
int main (int argc, char *argv[])
{
D_ d;
ieq (g_ (d), 101);
return 0;
}
==========================================================
Please help me regarding this.

------- Comment #1 from rguenth at gcc dot gnu dot org 2008-11-06 11:51 -------
Confirmed. For the following neither f_ nor d_ are dependent and should be
bound to f_ (B_ &) during first-stage name-lookup. For some reason this
doesn't work - it does if d_ is of type B_ though.
extern "C" void abort ();
struct B_ { };
struct D_:public B_ { };
D_ d_;
void f_ (B_ &) { }
template < class T >
void g_ (T t)
{
f_ (d_);
}
void f_ (D_ &) { abort (); }
int main (int argc, char *argv[])
{
D_ d;
g_ (d);
return 0;
}

Even the following fails
extern "C" void abort ();
struct B_ { };
struct D_ : public B_ { };
D_ d_;
void f_ (B_ &) { }
template < class T >
void g_ ()
{
return f_ (d_);
}
int main ()
{
g_<int> ();
return 0;
}
void f_ (D_ &) { abort (); }
where f_ (D_ &) must not be even in the 2nd stage name-lookup overload set.

We seem to not know if we bound f_ already. Instead another round of koenig

G++ has never done two-phase name binding; that's an area that needs work for
standards conformance. This testcase worked properly by accident in 3.4 and
4.0, because of an optimization which was disallowed under DR 164.

Doh. That seems to be a pretty important semantic piece of C++ though ;)
Thanks for fixing this bug so quickly.

* pt.c (type_dependent_expression_p_push): New fn.
(tsubst_copy_and_build) [CALL_EXPR]: Only do arg-dep lookup when the
substitution makes the call non-dependent. Preserve koenig_p.
* parser.c (cp_parser_postfix_expression): Only do arg-dep lookup
for non-dependent calls.
* semantics.c (finish_call_expr): Revert earlier changes.
* cp-tree.h: Revert change to finish_call_expr prototype.
