--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This one still happens on the trunk even with PR 107465 fixed. The reason is
because even though a warning here is correct, it is not wanted due to
requiring constant folding. Note you can get also the incorrect warning wording
at -O0 with constexpr in GCC 13+ (and -std=c2x).
