use lp:~elenst/randgen/mariadb-patches for RQG.
You might need to run it several times.
To run the test several times, you can use the following command
perl ./runall-trials.pl --trials=5 --grammar=enc1.yy --skip-gendata --threads=1 --queries=100M --duration=300 --basedir=/home/buildbot/10.1 --vardir=/home/buildbot/vardir1 --mysqld=--plugin-load-add=file_key_management.so --mysqld=--file_key_management_filename=/home/buildbot/10.1/mysql-test/std_data/keys.txt --mysqld=--innodb-encrypt-tables=ON

(adjust trials value as needed).
It will run the test until it fails, or the <trials> number of times, whichever happens first.
To run all <trials> test runs regardless the outcome, add --force to the command line.
It can be useful if you start getting different failures with this test, which might well happen.
