Description
When using version 1.3.0 of the audit plugin bundled in MariaDB 5.5.46 and 10.0.22 with MySQL 5.6, the server can crash. This crash was originally experienced with audit plugin version 1.1.8, and we thought it may have been caused by MDEV-7641. However, the crash still happens after upgrading to 1.3.0.
151106 18:20:19 server_audit: MariaDB Audit Plugin version 1.3.0 STARTED.

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.
|

|
key_buffer_size=33554432
|
read_buffer_size=131072
|
max_used_connections=5
|
max_threads=13100
|
thread_count=4
|
connection_count=2
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8596278 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...
