Hi,

Last night one of my servers updated MariaDB to 10.1.15 and it started 
to crash every few minutes since the update ( from 10.1.14 -> 10.1.15 ).

------------

160702 10:22:13 [ERROR] 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.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

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.

Server version: 10.1.15-MariaDB
key_buffer_size=268435456
read_buffer_size=524288
max_used_connections=8
max_threads=1001
thread_count=4
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 
1804821 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...

Anyone else encountered crashes on 10.1.15 ?
