Comment 6 for bug 896439

I just had an instance crash with a similar query.

select /*! SQL_NO_CACHE */ @a:='2013-01-14 14:57:00', @b:='(none)', @c:='10.20.36.131', @d:='3307', X.* from information_schema.INNODB_BUFFER_POOL_STATS as X

The instance is MyISAM only and I run it with skip-innodb.

Version: '5.1.66rel14.1' socket: '/san/mainolpanalytics/mainolpanalytics.sock' port: 3307 Percona Server with XtraDB (GPL), Release rel14.1, Revision 495

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.
Please help us make Percona Server better by reporting any
bugs at http://bugs.percona.com/

key_buffer_size=1073741824
read_buffer_size=131072
max_used_connections=14
max_threads=50
thread_count=10
connection_count=9
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1157930 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
