Hi,

I'm running kawa-1.6.70 w/ JDK-1.2.2.

kawa fails to load/compile the portable regular expressions by dorai
sitaram.
(see http://www.cs.rice.edu/~dorai/pregexp/pregexp.html,
 http://www.cs.rice.edu/~dorai/pregexp/pregexp.tar.gz)

==>

additionally, if I define:

(define (fac x save)
  (cond ((eq? x 0) 1)
        ((eq? x 1) 1)
        (else
         (* x (fac (- x 1))))))

kawa complains (right), but I guess it should not quit, as it does:

==>
<stdin>:144:11: warning - too few args for fac
<stdin>:144:11: internal error while compiling - caught:
java.lang.NullPointerException: 


any ideas?

Cheers,

Martin
