--- Comment #1 from Zhendong Su <su at cs dot ucdavis.edu> ---
The following (somewhat simpler) test case triggers the same ICE: 

---------------------

int a, b, c;

int
fn1 ()
{
  return a || b;
}

static void 
fn2 (int p)
{
  if (p)
    c = fn1 ();
  for (;;)
    ;
}

void
fn3 ()
{
  fn2 (1);
}
