------- Comment #9 from ebotcazou at gcc dot gnu dot org  2008-07-27 09:16 -------
This points to an immediate problem in vn_reference_op_compute_hash:

/* Compute the hash for a reference operand VRO1.  */

static hashval_t
vn_reference_op_compute_hash (const vn_reference_op_t vro1)
{
  return iterative_hash_expr (vro1->op0, vro1->opcode)
    + iterative_hash_expr (vro1->op1, vro1->opcode);
}

op2 is not hashed (whereas it is on the 4.3 branch).
