提交SR，MOS认为可能是Bug 6666870，给出以下方案:
There are a large number of possible bugs but Bug 6666870 is the most likely culprit. There is no one off patch available. 10205 is not yet available.

ACTION PLAN:
=============
1.Please disable Cost Based Transformation as a workaround, this can be done in the init.ora/spfile or at the session level, for example:
SQL> alter session set "_optimizer_cost_based_transformation"=off ;

2.Apply the 10205 patch set when it becomes available.

3.If the optimiser change fails to resolve your issue, please advise us of any recent changes to your DB or server?

4.In particular, did you recently apply the CPUJAN2008 Patch?
If so, please see Note.558901.1 Ext/Mod ORA-00600 internal error code, arguments [qctcte1] After Applying CPUJAN2008 Patch

5.If there is a function based index involved, please see;
Note.788124.1 Ext/Pub ORA-00600 [qctcte1] With Function Based Index Access

6.Changing your code to eliminate the parallel clauses may also act as a workaround.
