--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
That is because with the non pointer case gcc can figure out the alignment
without having to assume via pointers.

Note the original code is also undefined by the c standard even the non pointer
case you gave, it just happens to work is not a reason to depend on it.
