--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
DSE removes a few stores even though they are used in the check.

  _18 =3D .gnat_malloc (4);
  MEM[(integer *)_18] =3D 1; ;; this one
  FRAME.2.i =3D _18;
  _17 =3D .gnat_malloc (4);
  MEM[(integer *)_17] =3D 0; ;; this one
  FRAME.2.j =3D _17;
  c67005c.B_1.check (0); [static-chain: &FRAME.2]
  _16 =3D .gnat_malloc (4);
  MEM[(integer *)_16] =3D 0; ;; this one
  FRAME.2.i =3D _16;
  c67005c.B_1.check (1); [static-chain: &FRAME.2]
