--- Comment #7 from Andi Kleen <andi-gcc at firstfloor dot org> ---
Tamas also gave this example in PR115866 which shows the same problem:

short a[100];

int foo(int n, int counter)
{
   for (int i = 0; i < n; i++)
     {
        if (a[i] == 1 || a[i] == 2 || a[i] == 7 || a[i] == 4)
          return 1;
     }
    return 0;
}
