--- Comment #1 from ktkachov at gcc dot gnu.org ---
Just increasing the size of 'e' avoids undefined behaviour.
The following doesn't give a warning and still shows the bug:
int a, b, c, d;
int e[100];
void
fn1 ()
{
  int *f = &d;
  c = 6;
  for (; c; c--)
    {
      b = 0;
      for (; b <= 5; b++)
        {
          short g = e[(b + 2) * 9 + c];
          *f = *f == a && e[(b + 2) * 9 + c];
        }
    }
}
