This class of subtle bugs exists whether or not your GC is accurate as soon as you take the red pill and leave the VM environment. If you forget to add your C pointer to the accurate GC's root set, you're just as dead. Related story: http://news.ycombinator.com/item?id=217189
But that is by definition a tractable problem because the source will show that the root set isn't being used properly. (additionally, in practice this proves to be a rare and easy to fix bug)
