--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That can happen. Is the std::cbrt (123.456) precise (error <= .5ulp)? If so
and the library implementation is not, you should expect some differences.
std::cbrt is constexpr, so if you use it on a constant argument, the compiler
can (and in constant initializers/constexpr contexts must) fold it into a
constant.
