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...

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.

|
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
|
key_buffer_size=33554432
|
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.

where mysqld died. If you see no messages after this, something went

terribly wrong...
