MySQL FOSS License Exception We want free and open source software applications under certain licenses to be able to use specified GPL-licensed MySQL client libraries despite the fact that not all such FOSS licenses are compatible with version 2 of the GNU General Public License. Therefore there are special exceptions to the terms and conditions of the GPLv2 as applied to these client libraries, which are identified and described in more detail in the FOSS License Exception at <http://www.mysql.com/about/legal/licensing/foss-exception.html>.

GPLv2 Disclaimer For the avoidance of doubt, except that if any license choice other than GPL or LGPL is available it will apply instead, Oracle elects to use only the General Public License version 2 (GPLv2) at this time for any software where a choice of GPL license versions is made available with the language indicating that GPLv2 or any later version may be used, or where a choice of which version of the GPL is applied is otherwise unspecified.

Before this fix, the command SHOW ENGINE PERFORMANCE_SCHEMA STATUS could report wrong amount of memory allocated, when the amount of memory used exceeds 4GB. The problem is that size computations are not done using size_t, so that overflows do occur, truncating the results. This fix compute memory sizes properly with size_t. Tested manually. No test script provided, as the script would need to allocate too much memory for the test.
