      Description

      After a MariaDB upgrade from 5.5.37 to 5.5.41, it crashes on dynamical load of the server_audit.so.

      The sequence of the events:
      1. Stop Mariadb 5.5.37 and point the symlink to 5.5.41
      2. Commented the Audit Plugin Configuration in config file.
      3. Start the database and execute the mysql_upgrade script
      4. Check for audit vars:

      (root@localhost) [(none)]> show variables like "%audit%";
      Empty set (0.00 sec)

      5. Load the server_audit.so

      (root@localhost) [(none)]> INSTALL PLUGIN server_audit SONAME "server_audit.so" ;
      ERROR 2013 (HY000): Lost connection to MySQL server during query
      (root@localhost) [(none)]> select user from mysql.user;
      ERROR 2006 (HY000): MySQL server has gone away
      No connection. Trying to reconnect...
      Connection id: 2
      Current database: *** NONE ***

      Error log:

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
       
      To report this bug, see http://kb.askmonty.org/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.
       
      Server version: 5.5.41-MariaDB

      read_buffer_size=8388608
      max_used_connections=3
      max_threads=402
      thread_count=2
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 11566067 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
