------- Comment #5 from pinskia at gcc dot gnu dot org 2006-03-22 19:19 -------
The problem is the follow if is being hit:
2941 /* If OP is a constant that has overflowed, do not value number
2942 this expression. */
2943 if (CONSTANT_CLASS_P (op)
2944 && TREE_OVERFLOW (op))
Which means we don't get a VH correctly for this statement.
