Why would the alignment requirement be 8 ? On such a system
an implementation would probably pad the struct (which is allowed),
so sizeof(T) would be 16.
Robert replies
The padding has no effect on the alignment requirement, perhaps you
are misunderstanding the term. The alignment of this struct is most
certainly 8, whether or not it is padded.
