This code crashes Guile 2.0.11:

(define x (make-dynamic-state))
(with-dynamic-state x (lambda () (/ 1 0)))


For now I'm using this workaround:

(let ((w-d-s with-dynamic-state))
  (set! with-dynamic-state
        (lambda (s p)
          (let ((e #f))
            (w-d-s s (lambda ()
                       (catch #t p
                         (lambda x (set! e x)))))
            (when e (apply throw e))))))
