I know it's nonsensical, but (set! display #f) in a fresh interpreter
causes an infinite loop.

Interrupting with Ctrl+C exits guile.

I haven't currently a working Guile around to check (bad me, will
fix that!) but my guess is that Guile is trying to complain (via
an uncaught exception) that you're trying to mutate something you
should not and... is calling display for that. Which now is #f,
which is definitely a wrong type to apply.

Cheers
