Well, apart from the fact that UNIX-like systems have traditionally dumped core files in programs' working directories if they crash, so needing a script to clean them up.

Linux still does, though many distros set ulimit or /proc/sys/kernel/core_pattern to disable it.

Windows does this too, except it hides them in it's system folders, it even comes with a built in clean-up script you can run. Not a problem that is worse on *nix.
