--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is not a bug.
Without -fpacked-struct, e.b and e.d.c does not have any bits in common due to
a padding field in `struct a` because of the alignment of short is 2. But with
-fpacked-struct, the padding byte/field goes away and you get an overlap.
