------- Comment #11 from rguenth at gcc dot gnu dot org 2007-03-15 17:28 ------- Note that either SCEV or ivopts derives a loop trip count of 1 wrongly out of the [1] sized array as it is a tail array. Why this happens in stage2 and not stage1 is of course a mystery if not (what is probably the case) tree-scalar-evolution.c, tree-chrec.c or tree-ssa-loop-ivopts.c is miscompiled.
