--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
What precisely is causing the problem?  Are we doing something like mucking=

the loop closed ssa form?  Or do these passes have internal data that's
invalidated by the PHI changes?  Or something else?

Hard to know what to recommend here without  more info.=
