Getting different error for different users

Hi All,

I am getting the following error while trying to run a list report:
RQP-DEF-0177 An error occurred while performing operation ‘sqlPrepareWithOptions’ status=’-9’. DPR-ERR-2082 An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2015-01-07-10:06:56.987-#39

While trying to run the same report as Admin getting the following error:
RQP-DEF-0177 An error occurred while performing operation ‘sqlPrepareWithOptions’ status=’-9’. UDA-SQL-0107 A general exception has occurred during the operation “prepare”. ORA-00600: internal error code, arguments: [kkoipt:invalid aptyp], [0], [0], [], [], [], [], [], [], [], [], []

Can someone please help me with the error.

Thanks in Advance
