ORA-00600: internal error code

Hi, guys!
This error appeared when some Java Developer try to make a simple SELECT Statement through Java. After little investigation in alert.log and then in trace file I found this prblem recorder in trace file:
"ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []
Current SQL statement for this session:
SELECT VALUE FROM NLS_INSTANCE_PARAMETERS WHERE PARAMETER ='NLS_DATE_FORMAT'
----- Call Stack Trace -----
calling call entry argument values in hex
location type point (? means dubious value)
-------------------- -------- -------------------- ----------------------------
Cannot read string table section header in /lib/libm.so.6."
This is not exact SELECT statement which he querying, but this error is in whole trace file:
Cannot read string table section header in /lib/libm.so.6.
Is anyone experienced the same problem.
I will appreciate your help and opinions.
Thanks in advance
