The conditional store pass is confused about

  *D.1952_4 = 0;
  D.1953_5 = i_1(D) & 1;
  if (D.1953_5 != 0)
    goto <bb 3>;
  else
    goto <bb 4>;

<bb 3>:
  MEM[(char * {ref-all})D.1952_4] = "";

because that assignment is an array-to-array assignment (not exactly
optimal result of constant-folding).
