  Target Milestone: ---

Affects versions down to at least r5 :


$ cat z1.f90
program p
   integer, parameter :: a(:) = [1, 2]
   integer :: x(2)
   data x /a(:)/
end


$ cat z2.f90
program p
   character(3), parameter :: a(:) = ['123']
   character(3) :: x(1)
   data x /a(:)/
end


$ cat z3.f90
program p
   character, parameter :: c(:) = ['1', '2', '3']
   type t
      integer :: a
      character :: b(3)
   end type
   type(t) :: x = t(1, c(:))
end
