Expression_cache_tmptable object uses an Expression_cache_tracker object to report the statistics. In the common scenario, Expression_cache_tmptable destructor sets tracker->cache=NULL. The tracker object survives after the expression cache is deleted and one may call cache_tracker->fetch_current_stats() for it with no harm. However a degenerate cache with no parameters does not set tracker->cache=NULL in Expression_cache_tmptable destructor which results in an attempt to use freed data in the cache_tracker->fetch_current_stats() call. Fixed by setting tracker->cache to NULL and wrapping the assignment into a function. |

MariaDB: drop-in replacement for MySQL
MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Foundation and the MariaDB Corporation, and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
Help:
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
