Crash occurs during some commands' interpretation

[yluo]

Hello,

I met some crashes after I installed guile-1.6.4 in IA.64 machine, below 
is the information I saw:

--------------------------------------------------
guile> (define call/cc call-with-current-continuation)
guile> (define retry #f)
guile> (define factorial
 (lambda (x)
   (if (= x 0)
       (call/cc (lambda (k) (set! retry k) 1))
       (* x (factorial (- x 1))))))
guile>  (factorial 4)
24
guile> (retry 1)
Segmentation fault (core dumped)


guile> (display (let ((x (call-with-current-continuation (lambda (k) k))))
          (x (lambda (ignore) "hi"))))
Illegal instruction (core dumped)
---------------------------------------------------

Please give me your precious suggestion. Thanks a lot!!!

Best Regards,
Pavane
