Ah, that came after his original report 
<http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00182.html>, 
which is the one I was referring to. I reproduced the later problem, and 
as near as I can make it out it is due to an incompatibility between 
vfork and -fsanitize=address. My guess is that the vforked child 
corrupts the parent's shadow memory. I worked around the problem by 
installing the attached patch into Emacs.
