[Bug fortran/32985] New: Derived type variables need SEQUENCE attribute to be in a COMMON

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

"C589 (R558) If a common-block-object is of a derived type, it shall be a
sequence type (4.5.1) or a type with the BIND attribute and it shall have no
default initialization."

A default initializer is also accepted.

Testcase based on the invalid gfortran.dg/namelist_14.f90:

!{ dg-do compile }
module global
  type             ::  mt
    integer        ::  ii(4)
  end type mt
end module global

program namelist_14
  use global
  common /myc/ cdt
  type(mt)         ::  cdt
end program namelist_14

! { dg-final { cleanup-modules "global" } }
