So it seems like CCL crashes in the CALLBACKS.QSORT test (in
cffi/tests/callbacks.lisp) somewhere within the call to qsort(). I
would guess there is some bug related to callbacks. Try this:

(ccl:defcallback qsort-callback (:address a :address b :signed-int)
  (let ((x (ccl:%get-signed-long a))
        (y (ccl:%get-signed-long b)))
    (cond ((> x y) 1)
          ((< x y) -1)
          (t 0))))

(defun test-callbacks-with-qsort ()
  (ccl:%stack-block ((array 40))
    (loop for i from 0
          and n in '(7 2 10 4 3 5 1 6 9 8)
          do (setf (ccl:%get-signed-long array (* i 4)) n))
    (ccl:external-call "qsort" :address array :signed-int 10 :signed-int 4
                       :address qsort-callback :void)
    (loop for i from 0 below 10
          collect (ccl:%get-signed-long array (* i 4)))))
