Garbage collection and root objects

Subject: Garbage collection and root objects

Hi, I'm having a problem with a simple garbage collected app in which my NSDocument subclass appears to be becoming invalid (without the finalizer being called though). This only happens on the release build, so I guess it's something to do with the optimizing compiler using a less conservative garbage collection scheme.

My best guess is that I'm not marking the document as a root object. Do I need to jump through extra hoops to stop the GC touching this object, or is my bug elsewhere?

Thanks

Tom Davie
