PEF in Mach-O App crash - Puzzle

[Björn Eiríksson <bjorn at einhugur dot com>]

Hello

I just got a bug report from a user where a Mach-O app using a PEF 
plugin fails on a property, and I am not sure
yet how to report it, I was wondering if others are getting the same 
also.
Here is how the code is called from REALbasic:

  stack = new ObjectStack()

  stack.Push(new Date())   // The fact that this one is valid shows the 
object is alive
  i = stack.Size  // Crash (When the App is Mach-O, no Crash when the 
App is PEF)
  MsgBox Str(i)

(Note that the plugin is always PEF only)


long ObjectStackGetSize(REALobject instance,long param)
{
	DebugStr("\pIn ObjectStackGetSize");  // In a Mach-O App then we never 
ever get here
        ClassData(ObjectStackClass, instance, ObjectStackStruct, me);
        
        return me->m_Count;
}

REALproperty ObjectStackProperties[1] = {
        { nil, "Size", "Integer", 0, (REALproc)ObjectStackGetSize,nil,0},
};

I tried adding a Setter also to see if it was the fact that its read 
only that causes the crash.
I tried with and without the "long param", and tried with and without 
the zero for the field offset.
So if I am not missing something very obvious here then I don't get it 
why no-one has hit the problem before, other plugin authors, my self or 
even REALsoftware in their own built in plugins.
(And note we are talking about REALbasic 5.5.x here)
