Bug in Oracle 10.2.0.1.0-10.2.0.3.0: Sorted Hash Cluster

Question

I found another bug in Oracle:
SQL> create cluster tfsys_cluster
2 (
3 name varchar2(30),
4 cdp number(6),
5 stime number(6) sort)
6 hashkeys 1000
7 size 100;
SQL> create table tfsys(
2 name varchar2(30) not null,
3 cdp number(6) not null,
4 stime number(6) not null,
5 data number(10,2))
6 cluster tfsys_cluster(name, cdp, stime);
SQL> alter table tfsys add constraint tfsys_pk primary key(name, cdp, stime);
SQL> begin
2 for i in 1..5 loop
3 insert into tfsys values('IANC', 1, i, 15.25 + i);
4 end loop;
5 end;
6 /
SQL> commit;
SQL> select * from tfsys where name='IANC' and cdp=1 and stime <= 3;
NAME CDP STIME DATA
IANC 1 1 16,25
IANC 1 2 17,25
IANC 1 3 18,25
SQL> select * from tfsys where name='IANC' and cdp=1 and stime < 3;
NAME CDP STIME DATA
IANC 1 1 16,25
IANC 1 2 17,25
IANC 1 3 18,25
SQL> select * from tfsys where name='IANC' and cdp=1 and trunc(stime) < 3;
NAME CDP STIME DATA
IANC 1 1 16,25
IANC 1 2 17,25
This bug exists in Oracle 10.2.0.1.0-10.2.0.3.0 for Windows installation, for example in Oracle 10.1.0.3.1 for Red Hat 3 this query work right.

Answer 1

FWIW I have not been able to reproduce your problem on Windows.
I am getting the same results in Windows and Linux.
You should check if the execution plan is different in both cases
