This is a very simple heap implementation that allocates memory so that the end of each allocation always coincides with a page end and is followed by a guard page which is marked non-present. Out of bounds access (both read and write) therefore cause a crash (unhandled page fault). Note that this allocator is neither speed nor space efficient, indeed it wastes huge amounts of pages and address space so it is quite easy to hit limits. It is intended as a pure debug feature.
