------- Comment #2 from rguenth at gcc dot gnu dot org  2006-02-22 16:23 -------
I get

<bb 2>:
  #   SFT.0D.1534_2 = V_MUST_DEF <SFT.0D.1534_1>;
  aD.1532.iD.1521 = 1;
  #   SFT.0D.1534_3 = V_MAY_DEF <SFT.0D.1534_2>;
  bar (&aD.1532);
  #   SFT.0D.1534_4 = V_MAY_DEF <SFT.0D.1534_3>;
  bar2 (aD.1532);

for this case.
