I am running Emacs version 21.3 on a Linux x86_64 machine.
When I start up Emacs, I go to the *scratch* buffer and eval
(substitute-in-file-name "/~/")
and I get the expected result
"~/"
After running for a while, I notice that filename completion starts
giving errors. At this point, I re-try the above experiment:
(substitute-in-file-name "/~/")
But now, I get:
"/~/"
I am not able to figure out what happened in between to make it stop
working correctly. A search for "substitute-in-file-name" in
bug.gnu.emacs didn't turn up anything relevant to this problem.
I narrowed the problem down to substitute-in-file-name after some
debugging. Here's the sequence:
In the recently launched Emacs session, while editing a file, I type
C-x C-f to open another file.
In the minibuffer, I see the prompt "~/DesignDB/" (my current working directory)
I type "~/Al" so that the minibuffer now reads "~/DesignDB/~/Al"
I hit <TAB> to do completion on ~/Al
The minibuffer changes to "~/Alps/", which is correct.
In the older Emacs session where I see the problem, I carry out the
same sequence.
With the minibuffer reading "~/DesignDB/~/Al", I hit <TAB>
The minibuffer shows this message: "Opening directory: no such file or
directory, /nfs/pdx/home/mmohan/DesignDB/~*/Al"
The *Messages* window contains this message:
read-file-name-internal: Opening directory: no such file or directory,
/nfs/pdx/home/mmohan/DesignDB/~*/
I debugged this difference in complete.el and ffap.el until I reached
the above discrepancy in the behavior of built-in function
substitute-in-file-name. I was then able to make the 2 sessions
exhibit the difference with the minimal arg "/~/" to the function.
Hope that is sufficient info. Thanks,

What does
(find-file-name-handler "/~/" 'substitute-in-file-name)
return?
Andreas.

In both Emacs sessions, it returns nil.

Unfortunately, this seems a rather obscure problem, and Emacs 21 is
quite old, so you are unlikely to get much help unless you can give a
simple recipe showing how to get into this state (starting from emacs
-q --no-site-file). In any case, I would recommend upgrading to Emacs 23.

I was afraid you were gonna say that... :-) Unfortunately I haven't
been able to pin down the exact recipe; in the "good" session, I'm
still chugging along and the error hasn't occurred yet.
Thanks for your help anyway! If I figure out the recipe to trigger
this behavior, I will get in touch with you again.

Why do you do that instead of upgrade to Emacs 23?

Sorry, didn't notice your question earlier... yes, I will upgrade at
least to 22.3 (that is the latest version that our IT group has
installed internally). But I have quite a bit of customization, which
takes a while to transition, so it will probably be some time before I
can switch versions. So, if I notice the bug before that happens,
maybe I can figure out what triggers it -- that's what I meant.
Thanks,
