My guess is that when you run it from the command-line, debugging is
disabled by default (conversely, it is enabled by default at the REPL).
Thus, `(make-stack #t)' returns `#f', hence the `wrong-type-arg' later
on.

For this to work, you need to explicitly enable debugging using
something like "(debug-enable 'debug)".

Hope this helps,
Ludovic.
