I have a simple case where CLASS(*) leads to an ICE.

If it doesn't fit here, please feel free to move it elsewhere.



module gfcbug121

  implicit none

  type myobj

     class(*), allocatable :: x

   contains

     procedure :: print

  end type myobj

contains

  subroutine print(this)

    class(myobj) :: this

  end subroutine print

end module gfcbug121



I get:
