--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Thanks for the bug report, confirmed.  Started with r11-7931.

Reduced reproducer:

template <bool> using enable_if_t = int;
template <class> bool has_P_match_v;
template <template <class> class... List> enable_if_t<has_P_match_v<List...>>
a;
