--- Comment #1 from ktkachov at gcc dot gnu.org ---
I also see this ICE on this testcase on aarch64:
int a, b, c, e;
int d[1];
void
fn1 ()
{
  for (; b;)
    for (; c; c++)
      {
        a = 0;
        for (; a <= 1; a++)
          d[a] = e = b;
      }
}

at -Ofast -floop-nest-optimize
but with ISL 0.14, not 0.15
