gfortran 6.4, 7.3, and 8.2 all produce the error message below when
attempting to use a renamed type in the same scope as the variable that
motivated the renaming:

$ cat foo.f90
module foo
  type config
  end type
end module
  use foo, only: foo_config =3D> config
contains
  subroutine cap
    integer config
    type(foo_config) extra
  end subroutine
end

$ gfortran foo.f90
foo.f90:9:26:

     integer config
                  2
     type(foo_config) extra
                          1
Error: The type =E2=80=98config=E2=80=99 cannot be host associated at (1) b=
ecause it is
blocked by an incompatible object of the same name declared at (2)
