My libffi port to intel doesn't seem to be entirely correct. Just  
good enough to fool my by passing all pyobjc unittest, but not good  
enough to be actually useful.  Fixing this requires C, x86 assembly  
knowlegde and time. I don't have much of the later and am therefore  
not making much progress on this. But this will be fixed, I have an  
intel macmini that I want to use PyObjC with :-)

I have a similar bug that crashes my app on Intel, but works when running t=
he Universal binary on PPC machines. I whittled this down to a sample tonig=
ht, and here it is:

#<code language=3D"Python">
class NSStatusPyobjCResearchAppDelegate(NibClassBuilder.AutoBaseClass):
    statusBar =3D None
    statusMenu =3D None
    statusSub =3D None
   =20
    def applicationDidFinishLaunching_(self, aNotification):
        self.statusBar =3D NSStatusBar.systemStatusBar()
       =20
        self.statusMenu =3D self.statusBar.statusItemWithLength_(NSVariable=
StatusItemLength)
        self.statusMenu.setHighlightMode_(True)
        self.statusMenu.setTitle_(u"HMM")
        self.statusSub =3D NSMenu.alloc().initWithTitle_(u"SM")
       =20
        self.statusMenu.setMenu_(self.statusSub)
       =20

#</code>

(I can send you the complete sample project I made, if you wish.)


Which produces the following crashlog (snipped for brevity):

After making sure it Wasn't Just Me (I created an Objective-C translation a=
nd that worked like a charm), I submit it to the list in the hope that this=
 will help Wiser Folk track down issues.

Hope this helps,
