I don't know what I did. After rechecking I found that r202804 gives the ICE
and r202825 does not.

The error is now

pr57129.f90:2.8:

  type t
        1
Error: FUNCTION attribute conflicts with SUBROUTINE attribute in 't' at (1)
pr57129.f90:3.5:

  end type t
     1
Error: Expecting END SUBROUTINE statement at (1)
pr57129.f90:4.18:

  type, extends(t) :: t2
                  1
Error: Symbol 't' at (1) has not been previously defined
pr57129.f90:5.5:

  end type t2
     1
Error: Expecting END SUBROUTINE statement at (1)

The errors such as

Error: Symbol 't' at (1) has not been previously defined

comes from r202823.

So r202823 is likely to have fixed this PR.
