--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed that it is ifcombine. Not sure if I'd call it wrong-code though.
Note that there are no default-defs involved thus ifcombine doesn't see
must-uninits and disabling its transform when maybe-uninits are seen
is IMHO bogus.
Not sure what to do about this one. There is no way to preserve evaluation
order (no andif / orif on gimple).
