LWM: ENSURE-OBJC-INITIALIZED causes SEGV / Creating a pure Cocoa app

Hello,

I'm trying to create a "pure" Cocoa app (i.e. one which uses  
NSApplication and its event loop) with LWM 4.4.5 on Mac OS X 10.4.1.  
Has anyone out there tried something like this with success?

So far all my attempts have resulted in an app which dies while  
calling (objc:ensure-objc-initialized ...)

Error: Signal : segmentation violation(11)

Type :b for backtrace, :c <option number> to proceed,  or :? for  
other options

The only code which I'm loading into LispWorks is:

cocoa-application.lisp
==============================
;;; -*- Mode: Lisp; -*-

(defpackage :cocoa-application
   (:use :common-lisp)
   (:export
    #:*frameworks-to-initialize*
    #:start-application))

(in-package :cocoa-application)

(defparameter *frameworks-to-initialize*
   '("/System/Library/Frameworks/Foundation.framework/Foundation"
     "/System/Library/Frameworks/Cocoa.framework/Cocoa"))

(defun start-application ()
   ;; initialize objc runtime
   (objc:ensure-objc-initialized :modules *frameworks-to-initialize*))
===============================


Then in order to deliver the application I'm using the following  
script and command:

deliver.lisp
========================
(in-package "CL-USER")

(load-all-patches)
(load (sys:example-file "configuration/macos-application-bundle.lisp"))

(compile-file "cocoa-application.lisp")
(load "cocoa-application")

(deliver 'cocoa-application:start-application
      (write-macos-application-bundle
       "~/Test"
       :template-bundle "/Applications/LispWorks 4.4.5/Library/lib/ 
4-4-0-0/examples/delivery/macos/templates/FullApplication.app/")
      0
      :interface nil
      :multiprocessing nil)
==========================

% /Applications/LispWorks 4.4.5/LispWorks.app/Contents/MacOS/ 
lispworks-4-4-5-darwin -siteinit - -init deliver.lisp

My expectation was that the resulting app would simply start up and  
then exit cleanly. Does anyone know what additional initialization  
LispWorks does normally? Any ideas on why objc:ensure-objc- 
initialized is dying?

Any help would be much appreciated.

Thanks,

-greg
