The library returns addresses which may not be from the top of the 
allocated object. For some pre-calculated values, I actually use a 
shared memory pool.

I really need to be able to 'wire' this address directly into the SEXP.

Like I wrote in another message, changing the GC code (if necessary) 
could be a viable option.

I really like this approach, it would turn useful for many other 
projects :).

Thanks
