I'm confused: since you patched unexecw.c to set __malloc_initialized
to zero, the dumped Emacs should have called malloc_initialize_1,
which should have allocated a new copy of _heapinfo, that was supposed
to be consistent with the current heap.  Why isn't that working? why
`block' still gets a value that is relative to the "old" _heapinfo?
