differently. Is there any way that I can parameterize the invocation
of the two versions or at least set them up so as to allow each one
to load its own separate version of the dotemacs? For now I use the
cvs version only for its more complete documentation and for tutorial
purposes since it won't run for longer than a couple of hours without
causing a segmentation fault.

There are a couple of options.
Either launch emacs with "-q -l ~/.emacs.22" (or what ever file
you want to use). Or alternatively you could use the emacs-version variable, and have your .emacs work appropriately. You'd need check that your `custom-file' is being set appropriately. Incidentally, emacs should not seg fault after a couple of hours. I'm using the emacs-w32 from here.

I use the unpatched version without the W32 integration layer. This works well for me. I think I got it to core dump once, but not repeatedly.


I use something similar to this in my .emacs:

      ( (equal emacs-version "21.3.1")
    (setq custom-file "~/.emacs-cust-21.3.el"))
      ( t
    (setq custom-file "~/.emacs-cust-cvs.el")))
  (when (file-exists-p custom-file)
     (load custom-file)))

If you want to switch between different installed versions of Emacs you can use "usethis.exe" that comes with EmacsW32 and should be in the emacs\bin directory. This will change "emacs_dir" in the Registry so that gnuclient will select the one you have choosen.

I am using the patched version of Emacs that is available on the site above. I do not think I have seen any core dumps at all. Have you tested that version? Do you see any crashes with this version? Do you have more information about the crashes? (See "Bugs" in the Emacs info.)
