[Bug fortran/31306] New: ICE with implicit character variables

[fxcoudert at gcc dot gnu dot org]

No time to reduce this one, filing it so it doesn't get lost:

module cyclic
   implicit none
   contains
      function ouch(x,y)
         implicit character(len(ouch)) (x)
         implicit character(len(x)+1) (y)
         implicit character(len(y)-1) (o)
         intent(in) x,y
         character(len(y)-1) ouch
         integer i

         do i = 1, len(ouch)
            ouch(i:i) = achar(ieor(iachar(x(i:i)),iachar(y(i:i))))
         end do
      end function ouch
end module cyclic

program test
   use cyclic
   implicit none

   write(*,*) ouch('YOW!','     ')   
end program test

This is a case of cyclic specification so I have changed the keyword to
ice-on-ivalid.

Confirmed

------- Comment #5 from dfranke at gcc dot gnu dot org  2007-06-25 11:43 -------
The problem of the cyclic definition is (more or less), the same described in
PR24886, isn't it? E.g. replace

  implicit character(len(ouch)) (x)
  implicit character(len(x)+1) (y)
  intent(in) x,y

by

  character(len=*), intent(in)        :: x  ! or character(len=n), n integer
  character(len=len(x)+1), intent(in) :: y

to get a working binary. My meaning: "len(ouch)" is not known when defining the
length of the dummy argument x, thus it is a length that's different from the
actual length.
