I wrote a revised patch to emacs-25 (attached) which I hope addresses 
the former issue, by disabling randomization in both the undumped and 
dumped Emacs when Emacs uses its own allocator. Emacs already addresses 
the latter issue by re-execing itself when it changes personalities, so 
this shouldn't be an issue.
