--- Comment #4 from martin <mscfd at gmx dot net> ---
Just checked the patch and it works great, except that I can now easily produce
an ICE by changing (in sel_rank)
type(tuple), dimension(..), intent(in) :: x
to
class(*), dimension(..), intent(in) :: x
The ICE is
fc_get_descriptor_field, at fortran/trans-array.c:140
0x613e94 gfc_get_descriptor_field
../../gcc-repo/gcc/fortran/trans-array.c:140

Not sure whether this is an entirely new problem or related to the patch. At
least trans-expr.c6457 is just about 20 lines below the place where the patch
add the lines.
