This point deserves an explanation.
The W32 heap allocator can be used for a growable heap or a
non-growable one.
A growable heap is not compatible with a fixed base address for the
heap. Only a non-growable one is. One drawback of non-growable
heaps is that they can hold only objects smaller than a certain
size (the one defined below). Most of the larger blocks are GC'ed
before dumping. In any case, and to be safe, we implement a simple
first-fit allocation algorithm starting at the end of the
dumped_data[] array as depicted below:
