Unfortunately this is a case that I've never been able to solve in the
gccxml dump implementation. It works for members of class templates,
and for member templates of non-template classes. It does not work for
member templates within class templates. I have simply been unable to
discover the incantation inside GCC's source code to get a reference to
such instantiations. The class template instantiation lists the member
template, but the member template does not list its instantiations.
If you want to try to fix it, I can get you started.
