systemd could arguably be described as close to (maybe behind, maybe ahead of since it's the default for the most popular Linux distros) cron's level of ubiquity, and doesn't have this bug as far as we know.
What do you consider "actual cron"? Because the post specifically says Vixie cron, which has been the basis for most versions of cron on Linux systems.
