Zombie tracking....

[Lloyd Dupont]

I need to know not only if an object is deallocated twice (with zombies) 
but, also, when a zombie object is used inapproprietely.
I cannot even start my application with GDB (which is a .NET application), 
let alone debug it.
Problem is the ObjectiveC part of my application is opaque to 
VisualStudion.NET debugger.

What I would like to do is write a DebugObject which will poseAs: NSObject 
and when it is deallocated replace all its instance method pointer by an IMP 
of my making (which would, basicall, trace illegal call).

Any hint on how I could do that.
Constructing a fake isa pointer being a bit difficult I wonder if someone 
could provide me some example doing just that.
Ideally I neek this fake isa pointer to feature the same instance method 
pointer as the original, except they would all point to a method of my own 
making.
