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: 10.2.6-MariaDB-log
key_buffer_size=42949672960
read_buffer_size=1048576
max_used_connections=2433
max_threads=4001
thread_count=1230
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 50200296 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

We think the query pointer is invalid, but we will try to print it anyway.
