            Bug ID: 102620
           Summary: [12 Regression] ICE in gfc_get_array_span, at
                    fortran/trans-array.c:865
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

The result of len(c) or c%len is always a scalar.
It can't be an argument of size(x) where x must be an array.
Issue started between 20210530 and 20210606 :


$ cat z1.f90
program p
   character(3), allocatable :: y(:)
   y = ['abc', 'xyz']
   call s(y)
contains
   subroutine s(x)
      character(*) :: x(:)
      integer :: i
      print *, [(len_trim(x(i)), i=1,size(x%len))]
   end
end


$ cat z1b.f90
program p
   character(:), allocatable :: y(:)
   y = ['abc', 'xyz']
   call s(y)
contains
   subroutine s(x)
      character(*) :: x(:)
      integer :: i
      print *, [(len_trim(x(i)), i=1,size(x%len))]
   end
end
