Bugs fixed:
Partitioning: Security Fix: 
        Accessing a table having user-defined partitioning when the
        server SQL mode included
        ONLY_FULL_GROUP_BY caused the
        MySQL server to crash. For example, the following sequence of
        statements crashed the server:
      
DROP TABLE IF EXISTS t1;
SET SESSION SQL_MODE='ONLY_FULL_GROUP_BY';
CREATE TABLE t1 (id INT, KEY(id))
    PARTITION BY HASH(id) PARTITIONS 2;
Security Fix: 
        The strxnmov() library function could write a
        null byte after the end of the destination buffer.
