Tracked down to two patches. The first one (Roger Sayle) triggers an ICE, with
the  second one (Jan Hubicka) the ICE goes away, the comparision failure is
first seen, with only 3 differring files. Attaching the ofiles in a followup.

        * expr.c (expand_expr): The code following both_summands performs
        the same task as simplify_gen_binary.  Replace all gotos to
        both_summands with a call to simplify_gen_binary and delete the
        now unused label.
