Well, yes, we do generate that code.  However, the loop is unrolled
later on and the IR code on which the vrp complains later on actually is:

main ()
{
  unsigned int ivtmp.27;
  unsigned int pretmp.17;
  int pretmp.16;
  unsigned int pretmp.15;
  unsigned int anz.0;
  unsigned int D.1258;
  char * D.1259;
  int anz;

  # BLOCK 2 freq:909
  # PRED: ENTRY [100.0%]  (fallthru,exec)
  D.1259_28 = &formatstr[0][0];
  printf (&"%d %s\n"[0], 0, D.1259_28);
  D.1259_39 = &formatstr[0][100];
  printf (&"%d %s\n"[0], 1, D.1259_39);
  D.1259_50 = &formatstr[0][200];
  printf (&"%d %s\n"[0], 2, D.1259_50);
  D.1259_61 = &formatstr[0][300];
  printf (&"%d %s\n"[0], 3, D.1259_61);
  D.1259_72 = &formatstr[0][400];
  printf (&"%d %s\n"[0], 4, D.1259_72);
  D.1259_83 = &formatstr[0][500];
  printf (&"%d %s\n"[0], 5, D.1259_83);
  D.1259_94 = &formatstr[0][600];
  printf (&"%d %s\n"[0], 6, D.1259_94);
  D.1259_105 = &formatstr[0][700];
  printf (&"%d %s\n"[0], 7, D.1259_105);
  D.1259_116 = &formatstr[0][800];
  printf (&"%d %s\n"[0], 8, D.1259_116);
  D.1259_7 = &formatstr[0][900];
  printf (&"%d %s\n"[0], 9, D.1259_7);
  printf (&"   %d\n"[0], 10);
  return 0;
  # SUCC: EXIT [100.0%] 

}
