            Bug ID: 82589
           Summary: ICE in gfc_get_pdt_instance, at fortran/decl.c:3278
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

A combination of type-param-attr-spec LEN or KIND with another 
attribute like PRIVATE conflicts with f2008 4.5.3.1 :


$ cat z1.f90
module m
   type t(a)
      integer, len, private :: a
   end type
end
program p
   use m
   type(t(a=:)), allocatable :: x
   print *, x
end
