--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Slightly stupid example which currently fails with:
  sorry, unimplemented: target cannot support alloca.
  x86_64-none-linux-gnu-accel-nvptx-none-gcc returned 1 exit status

call foo(10)
contains
subroutine foo(nn)
  !$acc parallel
  block
    real :: array(nn), array2(10)
    array =3D [(3*i,i=3D1,nn)]
    !print *, array
    !$acc loop gang private(array)
    do i =3D 1, 10
      array(i) =3D i
      array2(i) =3D array(i)
    end do
    !print *, array
    !print *, array2
  end block
  !$acc end parallel
end
end=
