John, the ALIGN keyword doesn't force 16-byte alignment.  It just forces
integer and float types to be correctly aligned.  A 4F would cause the
DS to be at least 4-byte aligned; a 20i would cause the DS to be at least
8-byte aligned.

Only the presence of a pointer forces a 16-byte alignment (whether or
not you have ALIGN coded).

Even if a DS is always currently 16-byte aligned (is it?), it's not a
documented feature, and shouldn't be counted on.
