--- Comment #4 from Sebastien Bardeau <bardeau at iram dot fr> ---
I have pretty much the same kind of issue with gfortran 10.2.0 and 11.0.1
(20210426). The following code shows invalid results (printed lengths are 0=
).
Sometimes I even get a program crash. If the 'data1' component is a standal=
one
pointer (i.e. out of the derived type), I have no issue then.

program test2
  character(len=3D10), target, allocatable :: s(:)
  type :: pointer_typec0_t
    character(len=3D:), pointer :: data1(:)
  end type pointer_typec0_t
  type(pointer_typec0_t) :: co
  !
  allocate(s(3))
  s(1) =3D '1234567890'
  s(2) =3D 'qwertyuio '
  s(3) =3D 'asdfghjk  '
  !
  co%data1 =3D> s
  !
  print *,len(co%data1(1)),len_trim(co%data1(1)),co%data1(1)
  print *,len(co%data1(2)),len_trim(co%data1(2)),co%data1(2)
  print *,len(co%data1(3)),len_trim(co%data1(3)),co%data1(3)
end program test2=
