Is this the main problem with Emacs and draft-glibc-2.24 malloc? If so, 
can you suggest a patch to Emacs, or a patch to glibc, that will work 
around the problem? For example, can Emacs disable the aggressive ASLR 
somehow? I assume there is a relatively simple fix to Emacs or to glibc 
that could work around this specific problem. If it is a small and 
well-contained change to Emacs, I will advocate that it be squeezed into 
the next Emacs release.

Please bear in mind that I don't have easy access to that platform, and 
that my Internet connection is spotty right now so I can't do a lot of 
debugging myself.
