I can't remember why the bug is on me, but from test results, it was fixed in 10.0.4, possibly by the 5.6.10 merge (easily reproducible as described on 10.0.3, not reproducible on 10.0.4). Closing as fixed.
I have at least one problem, I'm not in mariadb group, can't run the test and I can't copy the files (not in sudoers).
