I believe this is something that should and can be addressed of at compile time by making Upp::Vector more robust.

I am surprised std::vector is guilty of the same problem. I will take a look to see if more recent standard library has fixed it.

CONSOLE_APP_MAIN
{
	typedef double Vector3[3];
		
	std::vector<Vector3> vector3_data(10);
}
