--- Comment #2 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Reduced:

auto consteval consteval_id(auto x) { return x; }

int main() {
  bool b = consteval_id(__builtin_is_constant_evaluated());
  if (!b)
    __builtin_abort();
}

Changed with r14-4140 "c++: Move consteval folding to cp_fold_r"
