Comment 5 for bug 1091072

It seems same problem still happens on the intermediate master with 5.5.48-37.8 when FLUSH LOGS is executed there on regular basis to get a chance to save/sync binary logs:

pure virtual method called
terminate called without an active exception
22:40:01 UTC - mysqld got signal 6 ;
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=8388608
read_buffer_size=131072
max_used_connections=45
max_threads=20002
thread_count=38
connection_count=38
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 43781150 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...

Please, take a look at the patch provided and consider implementing it.

There is nothing special in my.cnf (other than some binary and relay logs filtering).
