--- Comment #2 from kargl at gcc dot gnu.org ---
First, the compiler should not ICE.
Second, your program likely has a bug, which is the cause of the ICE.
Third, it's not clear if the middle-end can detect the issue.
Fourth, it's clear the Fortran front-end does not catch the problem.
Finally, here's a better reduced testcase.

program fix_track_partials

  implicit none

  integer, parameter :: double =3D 8
  integer, parameter :: lats100 =3D -4000,  dlat100 =3D 10
  integer, parameter :: jmax =3D 350
  integer  i, j

  integer, parameter:: &
      latt100(jmax) =3D [((lats100 + dlat100 * j - dlat100/2), j=3D1,jmax)]

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

   real(double), allocatable:: ys(:), ys_fixed(:)

   ys =3D [1]
   call move_to_nearest(ys_fixed, pnts=3Dys, axis=3Dlatt)

   contains

      subroutine move_to_nearest(res, pnts, axis)
         real(double), intent(out):: res(:)
         real(double), intent(in) :: pnts(:), axis(:)
      end subroutine move_to_nearest

end program fix_track_partials=
