The OP runs the Windows port, so this advice will probably not help.
(John, is that an MSVC build or a MinGW build?  "M-x emacs-version
RET" should tell you.)

The file etc/DEBUG has near its end some hints about debugging Emacs
on MS-Windows; I suggest that John reads that.  The text there doesn't
say how to interrupt Emacs (the equivalent of C-z on Posix platforms),
so perhaps someone here who knows how to do that could help you.
