I'm working on a test which emulates what Emacs is doing. It's not veryhard (just create something resembling a heap dump in the .datasection), it's just a little bit of work to get the self-checking right,without being able to use malloc to do any book-keeping.

Unfortunately, the existing tst-mallocstate test doesn't really say ifthe heap dump/undump logic is compatible with Emacs.
