Description:
try to run bacula backup software on MySQL-Cluster-server-gpl-7.2.7 and MySQL-Cluster-server-gpl-7.2.8
use 2 versions of bacula (5.0.3 and 5.2.12 - compliled with devel from mysql-cluster)
after running backup or recovery in bacula mysql server crash and is unable to restart
log after crash:
12:27:37 UTC - mysqld got signal 11 ;
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=8388608
read_buffer_size=131072
max_used_connections=2
max_threads=151
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338499 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...

Trying to get some variables.
Some pointers may be invalid and cause the dump to abort.
Query (7fb6e000e580): is an invalid pointer
Connection ID (thread ID): 15
Status: NOT_KILLED
How to repeat:
repeat every time - install mysql cluster, install bacula, create bacula database, run backup job - database crash immediately
