            Bug ID: 64943
           Summary: No error on ultimate allocatable components in IO list
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pault at gcc dot gnu.org

With this wrong code (other brand: Variables containing ultimate allocatable
array components are forbidden from appearing directly in input/output lists.
print *, TestReference([Test(99), Test(199)])):

  type :: Test
    integer :: i
  end type

  type :: TestReference
     class(Test), allocatable :: test(:)
  end type
print *, TestReference([Test(99), Test(199)])
end

5.0 gives:
