Get ORA-00600 when using ExecuteXmlQuery and NCLOB column

Question

I am using ODP.NET, I got the following exception:
at Oracle.DataAccess.Client.OracleCommand.XmlHandleException(OracleException
e)
at Oracle.DataAccess.Client.OracleCommand.XmlHandleException(OracleException
e)
at Oracle.DataAccess.Client.OracleCommand.ExecuteXmlQuery(Boolean wantResult)
at Oracle.DataAccess.Client.OracleCommand.ExecuteXmlQuery(Boolean wantResult)

uments\visual studio projects\datacentersolution\wikipedia\wikipediadumpxml.cs:l
ine 98
ORA-00600: internal error code, arguments: [kole_t2u], [34], [], [], [], [], [],
This is my code for retrieving data from database and save it into xml file.
The "TEXT" column in my select statement is NCLOB. When I leave TEXT column, my query works fine but with it I got exception.
please, I need help for resolving this issue.
// Open the connection
oraConn.Open();
OracleCommand selectCmd= new OracleCommand( String.Empty, oraConn);
selectCmd.XmlQueryProperties.RootTag = "Newspaper";
selectCmd.XmlQueryProperties.RowTag = "Article";
selectCmd.CommandText= "SELECT ID, TITLE, LANG, TEXT FROM NEWSPAPER_DATA WHERE LANG='en' AND ID=1";
selectCmd.XmlCommandType=OracleXmlCommandType.Query;
// execute xml request
XmlReader newsReader= selectCmd.ExecuteXmlReader();
// Read
while(newsReader.Read())
     string xmlfilename = row["TITLE"].ToString();
     using(TextWriter xmlWriter = new StreamWriter( this.DumpDirectory + xmlfilename + ".xml"))
          xmlWriter.Write( newsReader.ReadOuterXml());
// Close the newsReader
newsReader.Close();
oraConn.Close();
oraConn.Dispose();

Mark is correct, you will need to contact support. ORA-600 errors usually require you to patch the database or at least use a workaround to avoid the error.
