--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The patch also fixes an ICE for this code, taken from
https://stackoverflow.com/q/73498995/981959

program main

    integer, dimension(1:2) :: iii
    real, dimension(1:4,1:4,1:2) :: myArray

    associate(iix =3D> iii(1), iiy=3D> iii(2) )
    forall( iix=3D1:4, iiy=3D1:4 )
        myArray(iix,iiy,1) =3D iix + iiy
        myArray(iix,iiy,2) =3D (iix + iiy)*10
    endforall
    end associate

    print *, myArray(:,:,1)
    print *, myArray(:,:,2)

end program main


I know nothing about Fortran, but it looks sufficiently different to me that
maybe it's worth adding another test based on this code, so we don't regres=
s.

The question of whether to backport to gcc-10 or close this is still waiting
for an answer too.=
