bug#2309: Saving under Windows (sometimes) causes Emacs to freeze and allocate a lot of memory - Emacs 22.3.1

[Fredrik Hellman]

Hello!

I have downloaded and installed the following Emacs version for Windows:

GNU Emacs 22.3.1 (i386-mingw-nt5.1.2600)
 of 2008-09-06 on SOFT-MJASON

When I start emacs, open a file in a buffer, do some changes in it and
then saves the file with C-x C-s Emacs freezes and I can see how the
memory allocated by Emacs slowly increases until it after a few
minutes wakes up again and says in a separate buffer:

Emergency (alloc): Warning: past 95% of memory limit

This problem doesn't always occur on saves.

I don't know what more to tell, but if you want more details about
something, feel free to ask me.

Best regards,
Fredrik Hellman

Is there any pattern to when this occurs? Particular file types? Files 
saved in a particular location?

Try setting debug-on-quit to t (you can toggle this variable from the 
Options menu), then when you notice the problem, press C-g and see if 
you get thrown into the lisp debugger.

Thank you for the extra info you provided.

Emacs appears to be in an infinite loop trying to create the 
non-existent directory "d:/" and all its parents.
I've fixed make-directory to abort this loop when the directory is its 
own parent.
