--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is another testcase which shows the same behavior but turning off VRP and
a few others:
```
//-fselective-scheduling2  -O3 -fno-thread-jumps -fno-split-loops
-fno-tree-loop-ivcanon  -fsel-sched-pipelining
-fsel-sched-pipelining-outer-loops  -fno-tree-vrp -fno-tree-forwprop

int printf(const char *, ...);
int a, b[2] = {0, 0}, c;
void d() {
  int e, f = 0, f1 = 0;
  for (;;)
  {
    if (a) {
      for (e = 0; e < 5; e++) {
        printf("%d", b[e]);
        if (c)
          printf("\n");
      }
    }
    f = f+1;
    if (f!=2)
      f = 1;
    else
      return;
  }
}
int main() { d(); }
```

The behavior I think changes with the above testcase with r14-162 (but still
just a latent bug)
