--- Comment #6 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Another testcase (explicit underlying type):

enum E : int { x = 1, y = x << 1 };
template<E> struct A {};
A<x> a;

It appears this could be solved by *not* inserting const_decls of enums that
haven't been finished into the cv_cache.  I don't know how to do that though.
