The problem here is:

  #   predD.1714_2 = V_MUST_DEF <predD.1714_1>;
  predD.1714 = fD.1555;
  #   predD.1718_36 = V_MAY_DEF <predD.1718_9>;
  predD.1718.predD.1583 = &predD.1714;
  #   predD.1714_41 = V_MAY_DEF <predD.1714_2>;
  #   predD.1718_42 = V_MAY_DEF <predD.1718_36>;  <-- Notice this, this is because we had took its
       address at one point
  #   TMT.1D.1744_45 = V_MAY_DEF <TMT.1D.1744_31>;
  #   TMT.2D.1745_25 = V_MAY_DEF <TMT.2D.1745_30>;
  #   TMT.3D.1746_27 = V_MAY_DEF <TMT.3D.1746_28>;
  #   TMT.4D.1747_33 = V_MAY_DEF <TMT.4D.1747_26>;
  D.1738_32 = f ();
