If you want to limit the stack size within Guile, see
'call-with-stack-overflow-handler', described here:

If I create a simple recursive factorial function, and choose huge values for it, Guile will happily do my bidding and take all the system resources and my whole system becomes unusable. This should never happen. Python and other scripting languages usually limit how much of the system's resources they take up, and Python limit the depth of recursion (obviously not appropriate for Scheme). I planned to use GNU Guile for a small project, but I will most likely shift to another extension language because I cannot deal with this issue. Furthermore, can I make a polite recommendation that you shift over to a GitLab repository (git.gnu.io, like GNU fm and GNU social?), or something with a decent interface? The bug tracker is so old-fashioned, and submitting issues by email?! This might sound rude but I'm honestly trying to help. Worse still, you advertise support for ECMAScript on your website, but as far as I can tell, that's not really the case, since "The implementor was completely irresponsible". Am I mistaken? Finally, is Lua support under active implementation?
