--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
As for the ICE, reduced testcase is:
struct S { int s; };
struct U { int u; };

template <typename T>
consteval decltype (^^int)
foo ()
{
  return ^^S::s;
}

template <>
consteval decltype (^^int)
foo <U> ()
{
  throw 1;
}

template <typename T>
auto
bar (T x)
{
  return x.[: foo <T> () :];
}

auto
baz (U x)
{
  return bar (x);
}
