ORA-7445 core dump [kokscold()+849] from EM 12c

The first problem reported by my EM 12c is an ORA-7445 error. After checking the alert log following is the exact message:

Sun Feb 19 12:09:41 2012

The error seems to be coming from some automated scheduled SQL Tuning Task (Yet to figureout that). Searching at MOS gives reference to bug 9594372, which shows that the problem is with merge statement. It says that applying the patch will fix the issue.

While checking the error from my EM12c, it also gives a search button to search the error at MOS( I have already installed the MOS plug-in) which I found is very good thing as I need not to login to separate MOS windows.
