--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
tree-ssa-phiprop.cc at 8da568c885dc90ac5c7d9aee34ae78d5cfb8918c works,
at 952e145796da0f4dc96c42fdcabd75c8293d516c does not.  So it seems to be
r16-5555-g952e145796da0f which does not revert cleanly ontop of trunk,
so didn't try that.

Andrew?
