Hi Andrey, now I'm curious... is

alignas(int) unsigned char storage[sizeof(int)]; int* p1 = new (storage) int(1); int* p3 = new (storage) int(3); std::printf("%d\n", *p1);

different from

int* p1 = new int(1); int* p3 = new (p1) int(3); std::printf("%d\n", *p1);

or even

int p1 = 1; int* p3 = new (&p1) int(3); std::printf("%d\n", p1);

?

I don't think there's any difference here.
