I don't think this is valid code, reduced testcase:
template <class T> class a
{
  ~a<T>();
};

It's at least accepted by EDG and Comeau in strict-ansi mode.  (so, confirmed)

Don't take EDG/Comeau as conforming to the standard.

I don't believe the code is valid.

[mmitchel at gcc dot gnu dot org]

------- Comment #9 from mmitchel at gcc dot gnu dot org  2006-10-15 21:21 -------
There is long-standing confusion in the C++ standard regarding the naming of
destructors in various situations.  (Part of the issue is to what extent
destructors have names, and how the injection of class names into their own
scopes work, and how the lookup rules for qualified names apply to destructors,
and so forth.)  However, I do think this code should be accepted; it doesn't
look like one of the particularly tricky cases.
