Hi Stefan:

I haven't try snake anymore for a while. I Just tried it again and the
segfault is not there anymore (on master with my config and with
emacs -Q). This is mainly because it always creates the directory
~/.emacs.d/games independently of my answer when it asks. Is this
somehow intended or just an issue hiding the other?

Thanks for looking into this,
Ergus
