+GNU Emacs version 15 (15.34) was released sometime in 1984 or 1985 and

+/* Ben's capsule summary about expected and unexpected exits from XEmacs.
+
+ Expected exits occur when the user directs XEmacs to exit, for example
+ by pressing the close button on the only frame in XEmacs, or by typing
+ C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
+ buffers, and then exits using the primitive `kill-emacs'.
+
+ However, unexpected exits occur in a few different ways:
+
+ -- a memory access violation or other hardware-generated exception
+ occurs. This is the worst possible problem to deal with, because
+ the fault can occur while XEmacs is in any state whatsoever, even
+ quite unstable ones. As a result, we need to be *extremely* careful
+ what we do.
+ -- we are using one X display (or if we've used more, we've closed the
+ others already), and some hardware or other problem happens and
+ suddenly we've lost our connection to the display. In this situation,
+ things are not so dire as in the last one; our code itself isn't
+ trashed, so we can continue execution as normal, after having set
+ things up so that we can exit at the appropriate time. Our exit
+ still needs to be of the emergency nature; we have no displays, so
+ any attempts to use them will fail. We simply want to auto-save
+ (the single most important thing to do during shut-down), do minimal
+ cleanup of stuff that has an independent existence outside of XEmacs,
+ and exit.
+
+ Currently, both unexpected exit scenarios described above set
+ preparing_for_armageddon to indicate that nonessential and possibly
+ dangerous things should not be done, specifically:
+
+ -- no garbage collection.
+ -- no hooks are run.
+ -- no messages of any sort from autosaving.
+ -- autosaving tries harder, ignoring certain failures.
+ -- existing frames are not deleted.
+
+ (Also, all places that set preparing_for_armageddon also
+ set dont_check_for_quit. This happens separately because it's
+ also necessary to set other variables to make absolutely sure
+ no quitting happens.)
+
+ In the first scenario above (the access violation), we also set
+ fatal_error_in_progress. This causes more things to not happen:
+
+ -- assertion failures do not abort.
+ -- printing code does not do code conversion or gettext when
+ printing to stdout/stderr.

+ The line above is original. Unfortunately, when an error is tripped
+ inside of the handler (e.g. during Fbacktrace()), and the handler for
+ the handler is invoked, it correctly notices that something is amiss
+ and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
+ which causes the debugger to be invoked debugging the handler code in
+ this function -- and WITH THE STACK UNWOUND so that you see main()
+ calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
+ and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
+
+ There's some real weirdness going on in the stack handling -- unlike
+ in Unix, where further crashes just keep adding to the stack, it seems
+ that under the structured-exception-handling, the stack can actually
+ bounce back and forth between the full stack at the location of the
+ exception and the unwound stack at the place where the __try clause was
+ established. I don't completely understand it. What I do know is that
+ returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
+ aborting execution of the handler and going back to the outer filter
+ function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
+ hunky-dorey -- your debugger sees a crash at the right location with
+ the right stack.
+
+ I'm leaving in the trickier Unix-like code in the handler; someone who
+ understands better than me how the stack works in these handlers could
+ fix it up more. As it is, it works pretty well, so I'm not likely to
+ touch it more. --ben
