    Does the dumped Emacs crash even if you dump it immediately after
    temacs starts, without loading any of the Lisp files it loads during
    loading loadup.el (by hacking it to comment out all the load
    commands)?  If so, perhaps the amount of calls to malloc would be much
    smaller, and you could look at it.

It crashes on the first call to malloc.  That means the data
structures as dumped must be corrupted.  But I don't know what the
data structures of malloc look like, not nowadays.
