ANTIC_OUT[4] := { {view_convert_expr ,integer_cst 0} (0005) }
ANTIC_IN[4] := { {view_convert_expr ,integer_cst 0} (0005) }
S[4] := { {view_convert_expr ,integer_cst 0} (0005) }

so a quick look suggests we fail to properly fold references during PHI
translation.

<bb 4>:
  bar_34 = 0;

<bb 5>:
  # bar_11 = PHI <bar_33(7), bar_33(6), bar_34(4)>
  dest.12_29 = VIEW_CONVERT_EXPR<float>(bar_11);
