C-g worked. However, other things that I did resulted in
"Variable binding depth exceeds max-specpdl-size" messages.

I was using the "emacs-20111107-r106319-bin-i386.zip" Windows version.

The specific error message that I listed above:

  window-min-size-1: Variable binding depth exceeds max-specpdl-size

occurred when I tried to `C-SPC C-h M-w' the *Message* buffer.

When I was geting different "max-specpdl-size" errors with almost
everything I subsequently did, I started up a new Emacs instance in
order to file a bug report.

I then tried to copy the *Message* buffer from the original Emacs
instance that was having this problem into the new Emacs instance in
order to provide information for the bug report.

I could `C-x b' (switch-to-buffer) to the *Message* buffer and a few
other things but most things resulted in different "max-specpdl-size"
warning messages.

(BTW, I noticed that after sending a bug report and successfully
sending with `C-c C-c', the Bug Report Help buffer created when
invoking `(report-emacs-bug)' at least from the menu-bar, remains
visible as another (split) window.  Is that intentional?)
