When HttpCache is used, Response is loaded first, then the kernel is booted (on cache miss), which triggers the loading of classes.php. Since 3.2 generates a context free classes.php, the Response class is now included there when it was excluded previously. And boom, "Cannot declare class Symfony\Component\HttpFoundation\Response".
