[Bug c++/29469] New: error: non-template 'pair' used as template

[tbm at cyrius dot com]

The following example code compiled fine with 4.1.2 20060901 (Debian 4.1.1-13)
but fails with 4.1.2 20061007 (Debian 4.1.1-16).  I'm wondering whether this
change was intentional and whether there's a good reason for this change (in a
stable branch).

$ g++-4.1 -c pair.c
x.c:32: error: non-template 'pair' used as template
x.c:32: note: use 'avm_map<Key, Value, Compare, equal>::template pair' to
indicate that it is a template

The real question is avm_map dependent inside the nested class?
I know there are C++ defect reports asking that question so ...

And that is DR 224 which is in WP.

I think this is more complicated than just DR 224.

[Bug c++/29469] [DR 224] error: non-template 'pair' used as template

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2006-10-14 18:25 -------
DR 224 says this is invalid code but GDR has mentioned that DR 224 is broken in
really bad way:

template <class T> struct B : T
{
  void g(void) { B x; x.f(); }
}

struct A
{
  void f(void) {}
}

int main(void)
{
  B<A> t;
  t.g();
}

The above code would be invalid code with the resulution of DR 224.

Bugs waiting for the committee should not be release-critical; we can restore
this to P3 and reconsider the priority when unsuspending.
