At least that approach fails for the following file (of PSBLAS 3's configure),
which yields an
  internal compiler error: in cgraph_analyze_functions, at cgraphunit.c:1193

which is at
    fprintf (cgraph_dump_file, "\nReclaiming functions:");
  for (node = cgraph_nodes; node != first_analyzed; node = next)
    {
       ...
       gcc_assert (node->analyzed == node->local.finalized);

program xtt
  type foo
    integer :: i
  end type foo
  type, extends(foo) :: new_foo
    integer :: j
  end type new_foo
  class(foo), allocatable  :: fooab
  type(new_foo) :: nfv
  integer :: info
  allocate(fooab, source=nfv, stat=info)
end program xtt
