--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, part of the problem is union is forced to memory early on but then
optimized out but the object still exist in memory even though it is dead.
I am working on an optimization which improves this by the lowering of
bit-fields. But it won't go in until post GCC 9 (released next year).
