--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Note GCC only does NOT rejects the local variable case.
That is take:
int main() {
constexpr volatile int t = 1;
static constexpr volatile int t1 = t;
constexpr volatile int t2 = t;
constexpr int t3 = t;
};
GCC will reject t1 and t3 correctly but not t2.
So GCC is mostly correct except for that one case while MSVC accepts all of the
above.
