I recommend to use different names for the template parameters of the derived template, different from the names of the template parameters in the base class. Note that the warning also goes away if you compile with -pedantic. > I think, this is a compiler bug. The compiler warns you because it thinks you are using a compiler extension. In this specific case, you don't, but I doubt anybody would worry enough about this bug to fix it. The compiler produces correct code, after all. It might be still useful to file a bug report.
