Confirmed.  (there is a missed optimization here also which Richard G. and I am
looking at right now).

Anyways,
Before:
  # p_247 = PHI <&D.2477.a0.x[0](2)>;
<L183>:;
  #   TMT.32_246 = V_MAY_DEF <TMT.32_255>;
  *p_247 = 0B;

After:
#   SFT.12 = V_MAY_DEF <SFT.12>;
#   TMT.32_246 = V_MAY_DEF <TMT.32_255>;
D.2477.a0.x[0] = 0B;

We forgot to rename SFT.12.
