Okay, here it is:

https://drive.google.com/file/d/0B5QasYpFDUHeWGdsQ0RlWkk5Wm8/edit?usp=sharing

I was watching this in Task Manager; the emacs-X11 process got up to
around 400+ MB before dying with a segfault.

BTW, I am beginning to think that the link with Windows Update is a
red herring; I uninstalled all the updates from this morning, one by
one, and emacs-X11 still failed.  I then rolled back to a restore
point from a couple of days ago, again to no effect.  I don't know
what changed, though; everything was working fine until this morning.
