gfortran 13.0.0 20220925 snapshot (g:77bbf69d2981dafc2ef3e59bfbefb645d88bab9d)
ICEs when compiling the following testcase, reduced from
test/Semantics/selecttype01.f90 from the flang 15.0.1 test suite:

module c1162a
  type pdt(kind,len)
    integer, kind :: kind
    integer, len :: len
  end type
 contains
  subroutine foo(x)
    class(pdt(kind=1,len=:)), allocatable :: x
    select type (x)
    type is (pdt(kind=*, len=*))
    end select
  end subroutine
end module

% gfortran-13.0.0 -c lwe7niqj.f90
lwe7niqj.f90:10:14:
