FWIW: This time, the crash occurred (i.e., the fatal error dialog box
from Windows was displayed) when I did this:

I was using a different Emacs version (20).  I simply moved the mouse
over a frame of the development Emacs version (24).  IOW, I didn't even
touch the frame of the Emacs 24 version.  In principle, I was still
interacting with the Emacs 20 session.

At least that is what I think happened.  Very strange.  Maybe it means
something to you?

When mouse enters the Emacs frame, Emacs gets a message from Windows,
and processes it.

It's an assertion violation.

Thanks.  I have no idea how could the mouse face coordinates be
outside valid limits here, but I think I worked around the problem in
trunk revision 113778.
