Problem with posix-fork.

I can use posix-fork under 2.2, but under 3.0 it crashes. Here's an
example under 2.2:

hjstein:~/stk/www$ stk-2.2
Welcome to the STk interpreter version 2.2 [Linux-1.X-ix86]
Copyright (C) 1993,1994,1995 Erick Gallesio - I3S - CNRS / ESSI <eg_at_unice.fr>
STk> (require "posix")
"posix"
STk> (define (test)
  (let ((p (posix-fork)))
    (format #t "fork rtn: ~s\n" p)))

#[undefined]
STk> (test)
fork rtn: 198
#[undefined]
STk> fork rtn: 0
#[undefined]
STk> (exit)
hjstein:~/stk/www$


Here's version 3.0:

hjstein:~/stk/www$ stk-3.0b1

fork rtn: 216
#[undefined]
STk> fork rtn: 0
#[undefined]
STk> Segmentation fault

hjstein:~/stk/wwww$

Anyone have any idea what's going on?

Thanks,
