  ^^^^^^^^^^^^^^^^^^^^^^^^^
According to this, Emacs tried to display the Abort dialog box, and
crashed while trying.  You didn't see the Abort dialog, did you?

Maybe there's some Windows 8 specific problem in displaying that
dialog.  Of course, the main question is why did Emacs at all tried to
display the Abort dialog...
