mysqltest: Result content mismatch

Fails for me locally as well, but sporadically – sometimes at line 24, sometimes at line 36, sometimes both.

Repeating the problem does not seem to be very easy:

jan@jan-GE70-0NC-0ND ~/mysql/10.1-encryption/mysql-test $ ./mysql-test-run --vardir=/dev/shm encrypt_and_grep --parallel=4 --repeat=10
Logging: ./mysql-test-run  --vardir=/dev/shm encrypt_and_grep --parallel=4 --repeat=10

Perro with 20 iterations does not repeat, decreasing the priority.

We've had over 50 buildbot failures in the last 4 days, so it being not reproducible on Perro does not really make it any less important.
Please feel free to set the priority as you like, but fix it.
Besides, if something does not get encrypted only on certain machines, it makes the problem even more important, since it's harder to catch.

In fact, it fails just fine on perro.
I created a setup in the usual manner, please feel free to use it.

cd mdev8209/mysql-test
perl ./mtr encryption.encrypt_and_grep --repeat=10

1st run: 8 failures out of 20 tests.
2nd run: 15 railures out of 20 tests.

Output of these runs can be found in mdev8209/mysql-test/test.out and mdev8209/mysql-test/test2.out

It's a normal debug build (cmake . -DCMAKE_BUILD_TYPE=Debug).
