The type adjustment of template non-type parameters described in 13.2 [temp.param] paragraph 8 appears to be underspecified. For example, implementations vary in their treatment of
template<typename T, T[T::size]> struct A {}; int dummy; A<int, &dummy> a;
and
template<typename T, T[1]> struct A; template<typename T, T*> struct A {}; int dummy; A<int, &dummy> a;
See also issues 1322 and 1668.
Additional note, February, 2021:
See the discussion regarding top-level cv-qualifiers on template parameters when determining the type in this compiler bug report.
