Changes in MySQL 5.5.38 (2014-05-31)

   Bugs Fixed

     * InnoDB: For each insert, memset would be called three times to
       allocate memory for system fields. To reduce CPU usage, the
       three memset calls are now combined into a single call. (Bug
       #17858679, Bug #71014)

     * Certain INFORMATION_SCHEMA queries could cause a server exit.
       (Bug #18319790)

     * For indexes on prefixes or character string columns, index
       corruption could occur for assignment of binary data to the
       column due to improper character counting. (Bug #18359924)

     * Solaris-specific scripts were included in and installed by
       non-Solaris packages. (Bug #18305641)

     * EXPLAIN on a query with an EXISTS subquery containing a UNION
       could cause a server exit. Multiple executions of a prepared
       EXPLAIN on a UNION of subqueries could cause a server exit.
       (Bug #18167356)

     * Executing a correlated subquery on an ARCHIVE table which has
       an AUTO_INCREMENT column caused the server to hang. (Bug
       #18065452)

     * Calling mysql_get_server_version() with an invalid connection
       handler argument caused the client to exit. Now it returns 0
       and reports a CR_COMMANDS_OUT_OF_SYNC error. (Bug #18053212)

     * On Windows, calling mysql_thread_init() call without
       mysql_init() caused the client to exit. windows. Now it
       returns a nonzero result because it is an error to call
       mysql_thread_init() before the client library is initialized
       with mysql_library_init(). (Bug #17514920)

     * CMake produced not-useful warnings about
       INTERFACE_LINK_LIBRARIES policy. (Bug #71089, Bug #17905155,
       Bug #17894997)

     * LOAD DATA LOCAL INFILE could use all CPU if import errors
       occurred when there were no line delimiters. (Bug #51840, Bug
       #11759519)
