Initially discovered in Docker image: https://github.com/docker-library/mariadb/issues/29#issuecomment-152766835
But now it happens to me on Ubuntu 16.04 x64 while MariaDB 10.1 server itself works fine, problem is only with `mysqld --verbose --help`.
Debian Jessie, Ubuntu Trusty, Ubuntu 15.10, Ubuntu 16.04
x64 versions of above OSs are affected at least.
Happens on host system and under Docker image
