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)
