--- Comment #4 from ktkachov at gcc dot gnu.org ---
Seeing this on aarch64 with current trunk at -Ofast -floop-interchange with the
C testcase with ISL 0.15:

int a[1], c[1];
int b, d, e;

void
fn1 (int p1)
{
  for (;;)
    ;
}

int
fn3 ()
{
  for (; e; e++)
    c[e] = 2;
  for (; d; d--)
    a[d] = 8;
  return 0;
}

int fn5 (int);

int
fn2 ()
{
  fn3 ();
}

void
fn4 ()
{
  fn1 (b || fn5 (fn2 ()));
}
