mariadb with oq_graph server crash when running query from 2+ connections

Description

After following the example at https://mariadb.com/kb/en/oqgraph-examples/

when I run a query ""SELECT * FROM oq_graph WHERE latch='breadth_first' AND origid=1 AND destid=6;"
from two or more client connections I get ERROR 2013 (HY000): Lost connection to MySQL server during query
