--- Comment #1 from Tim Shen <timshen at gcc dot gnu.org> ---
I'm not sure whether the test case is valid.

A similar test case like this for <tuple> doesn't compile:

#include <tuple>

constexpr bool test() {
  std::tuple<int, void*> v{42, nullptr};
  auto const& cv = v;
  static_assert(std::get<0>(v) == 42, "");
  static_assert(std::get<0>(cv) == 42, "");
  return true;
}
static_assert(test(), "");

int main() {}
