I agree that this is not necessarily a good idea ;-), but notably

No. It definitely alters semantics, because programs with "hidden"
pointers will cease to function properly. These are legal C programs,
so by making them non-functional, you have altered semantics.
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.
