            Bug ID: 69859
           Summary: ICE on incomplete character declaration statement
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gerhard.steinmetz.fortran@t-online.de
  Target Milestone: ---

With an incomplete declaration :

$ cat z1.f90
program p
   type t
      character x y
   end type
end


$ gfortran-6 z1.f90
z1.f90:3:17:

       character x y
                 1
Error: Syntax error in data declaration at (1)
f951: internal compiler error: gfc_is_constant_expr(): Unknown expression type

---

Whereas, without embedding in type :

$ cat z2.f90
program p
   character x y
end


$ gfortran-6 z2.f90
z2.f90:2:14:

    character x y
              1
Error: Syntax error in data declaration at (1)
# no ICE
