Bug Description
I suppose, this is rather incompatibility than a bug, but should be fixed anyway.
May be disable userstat for SphinxSE engine?
The problem is: mysqld crashes on startup with sigsegv when having ha_sphinx.so plugin registered and userstat option enabled in my.cnf.
The first time I've loaded SphinxSE plugin it works just fine, but after shutdown mysqld keeps crashing on startup until I've disabled userstat in my.cnf.
Here is the log:
130704 19:32:52 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
130704 19:32:52 [Note] Plugin 'FEDERATED' is disabled.
15:32:52 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.
Please help us make Percona Server better by reporting any
bugs at http://
key_buffer_
read_buffer_
max_used_
max_threads=52
thread_count=0

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
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...
