--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note that GCC middle-end semantics would allow partial overlaps here unless
you factor in alignment requirements.
There is actually code in GCC9+ that is supposed to handle this situation but
for some reason it doesn't work here. I'll see why.
