closed as duplicate of:
Bug:13464002 - PREFETCH INVOLVING TEMP OBJECTS MAY RAISE ORA-600[KCBCHG1_12]/[KDIFIND:KCBGET_24

Bug:13464002 is fixed in RDBMS 12.1.

SOLUTION

To implement a solution for Bug:13464002, please execute any of the below alternative solutions:

Upgrade to 12.1 when it will become available.

OR
Apply patchset release 11.2.0.4 when it becomes available (not available as of time of publishing this article: JUL-2012) in which Bug:13464002 is fixed.

OR
Download and apply interim Patch:13464002, if available for your platform and RDBMS release. To check for conflicting patches, please use the MOS Patch Planner Tool. If no patch is available, file a Service Request through My Oracle Support for your specific Oracle version and platform.

OR
Use the workaround of setting "_db_file_noncontig_mblock_read_count"=0:

This parameter can be set only in the SPFILE and this requires a database restart:

SQL> ALTER SYSTEM SET "_db_file_noncontig_mblock_read_count"=0 SCOPE=SPFILE;

Restart the instance.

Explanation: 

Setting "_db_file_noncontig_mblock_read_count"=0 will disable prefetching of non-contiguous blocks.

To reset "_db_file_noncontig_mblock_read_count"=0 to its default value use: 

SQL> ALTER SYSTEM RESET "_db_file_noncontig_mblock_read_count";
