ORA-00600: internal error code, arguments: [qcsfbdnp:1], [], [], [], [], []

Question

Hi All,
When i try to execute the following query i am getting the error
ORA-00600: internal error code, arguments: [], [], [], [], [], [], [], []
and in the alert log file the error is
ORA-00600: internal error code, arguments: [qcsfbdnp:1], [], [], [], [], [], [], []
so please tell me the workaround to get rid of this. (db version:9.2.0.1,os:win 2000 Prof.)
Thankyou.
The query follows:

It seems the bug 2104392:" A query with nested CONNECT BY blocks and binds
in the START WITH clause or the FROM clause may fail with ORA-600 [QCSFBDNP:1]". You can find more information about this on Note:2104392.8 on Metalink. It is resolved on 9.2.0.2.
