--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Slightly more reduced testcase:
subroutine pr114883(a, b, c, d, e, f, g, h, o)
  real(8) :: c(1011), d(1011), e(0:1011)
  real(8) :: p, q, f, r, g(1011), h(1011), b, bar
  integer :: o(100), a, t, u
  p =3D 0.0_8
  r =3D bar()
  u =3D 1
  do i =3D 1,a
    do k =3D 1,1011
      km1 =3D max0(k-1,1)
      h(k) =3D c(k) * e(k-1) * d(km1)
      f =3D g(k) + h(k)
      if(f.gt.1.e-6)then
        p =3D min(p,r)
      endif
    end do
    q =3D 0.9_8 * p
    t =3D integer(b/q + 1)
    if(t>100)then
      u =3D t
    endif
    o(u) =3D o(u) + 1
  end do
end subroutine pr114883=
