Please be advised the queries that they are failing on are on table running on innodb engine. The Mariadb server runs fine when Columnstore is not there in the Mariadb server, but when Columnstore is added, it is failing on innodb engine "Outer join" queries.

170308 23:36:45 [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: 10.1.21-MariaDB
key_buffer_size=1098907648
read_buffer_size=2097152
max_used_connections=104
max_threads=602
thread_count=104
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3551255 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
