bug#56665: Segfault in SRFI-37 when raising ERROR in ARGS-FOLD

[Olivier Dion]

Hi,

I don't have a fix for you, but for what it is worth, it is possible to
avoid the segfault by wrapping the `args-fold` form with a
`with-exception-handle` with `#:unwind? #t` like so:

  (with-exception-handler
   (lambda (exn)
    (raise-exception exn))
   (lambda ()
    (args-fold ...))
   #:unwind? #t)
