--- Comment #10 from Paul Thomas <pault at gcc dot gnu.org> ---
See comment at rnflow.f90:899 - As Richard Biener suggested to the list
-fdefault-integer-8 fixes the problem but breaks tfft2 of the polyhedron su=
ite.

Better is:
      integer(8), parameter   :: jmul =3D  843314861  ! multiplicateur
      integer(8), parameter   :: jadd =3D  453816693  ! constante additive

Cheers
