Yes. I deleted emacs and just typed "make" to see how it is build, and
it is a dumped one, but now the behaviour is different, so I am restrating the

It seems that real_morecore is initialized to __morecore in two places:
ralloc.c:r_alloc_init (and after initialization, __morecore is set to

And in ralloc.c:r_alloc_reinit, but only for DOUG_LEA_MALLOC (and if emacs is
defined), and only if __morecore is not r_alloc_sbrk.

I think this r_alloc_sbrk is just to aviod an infinite loop if emacs is
linked statically (judging the comment).  So what I want to do as soon as
I have rebuild emacs from scratch to reproduce the original behaviour (doh!)
I will set a breakpoint on those init functions and see what happens.
