104 GNU Emacs version 15 (15.34) was released sometime in 1984 or 1985 and
105 shared some code with a version of Emacs written by James Gosling (the
106 same James Gosling who later created the Java language).

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

583 The line above is original. Unfortunately, when an error is tripped
584 inside of the handler (e.g. during Fbacktrace()), and the handler for
585 the handler is invoked, it correctly notices that something is amiss
586 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH,
587 which causes the debugger to be invoked debugging the handler code in
588 this function -- and WITH THE STACK UNWOUND so that you see main()
589 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(),
590 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH!
592 There's some real weirdness going on in the stack handling -- unlike
593 in Unix, where further crashes just keep adding to the stack, it seems
594 that under the structured-exception-handling, the stack can actually
595 bounce back and forth between the full stack at the location of the
596 exception and the unwound stack at the place where the __try clause was
597 established. I don't completely understand it. What I do know is that
598 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of
599 aborting execution of the handler and going back to the outer filter
600 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is
601 hunky-dorey -- your debugger sees a crash at the right location with
604 I'm leaving in the trickier Unix-like code in the handler; someone who
