[Bug c++/85944] Address of member variable of temporary not considered constexpr at global scope

--- Comment #2 from David Stone <david at doublewise dot net> ---
I have simplified the bug. It does not require a member variable to trigger the
bug, just taking the address of a a temporary bound to a reference function
parameter at global scope:



constexpr bool f(int const & x) {
    return &x;
}

constexpr auto x = f(0);





Note that this code does not trigger the bug:



int const & x = 0;
constexpr bool b = &x;
