In fact it's completely wrong.

  # __b_5 = PHI <&D.12083(48), __b_342(22)>;
<L18>:;
  #   VUSE <r_946>;
  #   VUSE <r_284>;
  #   VUSE <r_6>;
  #   VUSE <r_43>;
  D.12120_344 = *__b_5;

should be

  # __b_5 = PHI <&D.12083(48), __b_342(22)>;
<L18>:;
  #   VUSE <SFT.738_136>;
  #   VUSE <SFT.739_451>;
  #   VUSE <SFT.740_367>;
  #   VUSE <D.12083_947>;
  D.12120_344 = *__b_5;

This looks like a const vs. non-const issue (which I vaguely remember).
