--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is a frontend issue, the FE produces an invalid static initializer for
'latt' (DECL_INITIAL):

{(real(kind=3D8)) latt100[(integer(kind=3D8)) i + -1] / 1.0e+2, (real(kind=
=3D8))
latt100[(integer(kind=3D8)) i + -1] / 1.0e+2,... }

if this should be dynamic initialization FEs are responsible for lowering
this.

I don't know fortran enough for what 'parameter' means in this context:

   real(double),  parameter:: latt(jmax) =3D [(latt100(i)/100.d0, j=3D1,jma=
x)]

but the middle-end sees a readonly global (TREE_STATIC) variable.=
