Some other variants :


$ cat z3.f90
program p
   type t
      character a ,
      character b =
      character c :
      character d +
      character e .
      character f %
      !...
   end type
end


$ cat z5.f90
program p
   type t
      character, allocatable :: x(:) y(:)
   end type
end


$ gfortran-6 z3.f90
#...
