No, you'd get the default behavior of shared_ptr, a detached count.

Why would you want to do that? The whole point of the unified shared_ptr
interface is that different instances of shared_ptr<A> can use different
deallocators in the same program. If you need a COM smart pointer, why not
simply use one?
