Bulid log (native build on gcc76.fsffrance.org) can be found at
http://toolchain.lug-owl.de/buildbot/deliver_artifact.php?mode=view&id=4292383
for build
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=472655 .

So it's probably one of these two commits:

        r228586 = 54ac7405ce75c141dae33532d491d5793fb583e3
                Jan Hubicka  <hubi...@ucw.cz>
                Do not use TYPE_CANONICAL in useless_type_conversion

        r228585 = 5b4ada2a11ab19842d77296fc4b75971ddb07434
                Jeff Law <l...@redhat.com>
                [PATCH] Improve DOM's optimization of control statements

Haven't looked at the patches or what they're doing, but maybe you two
instantly recognize the issue?
