Dense Rank and Object types (oracle 9i and 10g difference).

Question

Hi all,
One of my queries in my procedure uses scalar subqueries and object types.
The code works fine in 10g but not in 9i. Both Object types and Dense_rank used below are present in both 9i and 10g.
The following is a part of a bigger query.. but this is what it comes down to when I zero in on the error.
-- In both 9i and 10g...
CREATE OR REPLACE TYPE t_audit_type as object(
   add_tms date,
   add_user_id varchar2(20),
   order member function match (t t_audit_type) return integer
Type created.
CREATE OR REPLACE TYPE BODY t_audit_type as
order member function match   (t t_audit_type) return integer is
begin
  if add_tms < t.add_tms then
     return -1;
  elsif add_tms > t.add_tms then
    return 1;
  else
    return 0;
  end if;
end;
end;
Type body created.
create table t ( x int, y date);
insert into t values(1, sysdate);
insert into t values(1, sysdate+1);

Thanks Dom for your reply.
Here is the message I found in the trace file for the error.
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [0000000100D72F84] [SIGSEGV] [Address not mapped to object] [0x000000018] [] []
Current SQL statement for this session:
select min(t_audit_type(x,y))
       keep(dense_rank first order by x)x
from tI will look in metalink and see if this has been addressed before.
Thanks...!
