[Bug 380709] [NEW] Crash in unit tests on AMD64

[wflu]

Public bug reported:

Binary package hint: clisp

A unittest in "tests/ffi.tst" (found in the clisp source package) segfaults in 64bit Ubuntu. Specifically, it seems like the following lines provokes the problem:
----
(progn
  (defparameter *x* 0)
  (defun callback (x)
    (the (unsigned-byte 16) x)
    (setf *x* x)
    (the (unsigned-byte 16) (1+ (* 2 x))))
  *x*)
0

(def-c-type idfun
 (c-function (:arguments (x uint)) (:return-type uint)
   (:language :stdc)))
IDFUN

;; convert forth and back
(type-of (setq callbackf (with-c-var (x 'idfun #'callback) x)))
FOREIGN-FUNCTION

(list (funcall callbackf 32767) *x*)
(65535 32767)
----

** Affects: clisp (Ubuntu)
