--- Comment #1 from anlauf at gcc dot gnu.org ---
Could be related to some other PRs involving initialization of derived types.
A missing check accepts invalid code, such as:

program m
  implicit none
  type t
     integer :: a(1) = [1, 2]
  end type
  type(t), parameter :: x(4) = t()
  print *, x
end

which prints:

           1           2           1           2

All versions tested down to at least 7 fail.
