--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
  parm 0 flags: nodirectescape
void e (int * d)
{
  int * * c.0_1;
  int * _2;

  <bb 2> :
  c.0_1 = c;
  _2 = b (d_4(D));
  *c.0_1 = _2;
  return;

is wrong, it does escape through the *c store.  I suppose b (d) is "wrong"
somehow, the escape through the return is not mentioned:

  parm 0 flags: direct noclobber noescape nodirectescape
int * b (int * d)
{
  <bb 2> :
  return d_1(D);
