Please help:Can't create sql object types

Fellow Oracler's,

This is a case in Solaris8, running Oracle Enterprise Server 8.1.7.0.0

If I do a simple:

SQL> create type t_address as object (

            2 street varchar2(15), city varchar2(15),
            3 city varchar2(15), state char(2),
            4 zip varchar2(9) );
            5 /

The Oracle Server comes with:

"Error at line 1
ORA-06544: PL/SQL internal error. Arguments [2603], [], [], [], [], [], [], []
ORA-06553: PLS-707: Unsupported construct or internal error [2603]"

Any clue about how to solve this problem will be greatly appreciated.

Thanks
