--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the original testcase except for test4, it is optimized for C++20 and not
C++17. Most likely because lambdas are considered constexpr if they can be
such. In test4 I suspect the uninit variable is making it not considered
constexpr.
