--- Comment #1 from Roy Crihfield <rscrihf at gmail dot com> ---
Getting the same behavior on 4.9.0 as stable release.

Rewriting the code to use a struct succeeds:

template <typename T, typename ...>
struct alias { using type = T; };

template <typename ...T>
using variadic_alias = typename alias<T...>::type;
