precise gc?

Hey party people!

What is the current state? Is it enough to store a pointer in a
ptrdiff_t variable instead of a pointer for the GC to ignore it or is my
current trick of simply inverting its value required?

If the trick is required, is it safe? Are there memory models in use
where the inverted pointer value might also be in GC memory?

Thanks!

Robert
