--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
This works as expected, in that we are getting the correct type for auto here:
```
#include <concepts>
#include <initializer_list>
template <typename T>
concept always_true = true;
template <typename T>
concept always_false = false;
template <typename>
inline constexpr bool is_init_list_v = false;
template <typename T>
inline constexpr bool is_init_list_v<std::initializer_list<T>> = true;
template <typename T>
concept not_init_list = !is_init_list_v<std::remove_cvref_t<T>>;
template <typename T>
inline constexpr bool not_init_list1 = !is_init_list_v<std::remove_cvref_t<T>>;
int main() {
auto f = {1, 2, 3};
static_assert(!not_init_list<decltype(f)>);
static_assert(!not_init_list1<decltype(f)>);
}
```
