Incorrect. As mentioned it can be configured as a drop-in replacement 
which is 100% compatible to legal C programs. Hidden pointers will work 
with malloc_uncollectable (which will be used in replacement mode), but 
will properly expose the malloced sections for GC scanning on objects 
that use GC-malloc.

So, just one of the misinformations floating around about Boehm-GC ;-) 
There are certainly issues with it, but actually it is pretty well 
thought out and provides a lot of options.

Greets,
