23.1.91; Cannot load .emacs-history from savehist.el

Sending this again, but with a much smaller attachment (46 KB), after having
pared down the file. I intended to send this new attachment as a reply to the
original bug report, but I never received that mail, so I couldn't reply to it.
I waited almost 7 hours.
I'm guessing that the original report was somehow lost or was perhaps rejected
because of the large (568 KB) attachment size (?). Dunno. (Seems like a
submitter should at least receive a rejection notice in that case, but I
So, apologies for creating a new bug, but I have no bug number from the first
report attempt to reply to. Hopefully this time it will get through. If the
original bug does get opened, then we can delete that. The original message is
below, so you have all the info in this bug report.

Subject: 23.1.91; Cannot load .emacs-history from savehist.el
Trying to load the attached file raises the error "End of file during
There is no real end-of-file problem, however: This file was created by
savehist.el using Emacs 23.1, and it loads fine in all releases of Emacs
(20 through 23). An error is raised only for the Emacs 18.104.22.168
NOTE: I had to attach a copy of the original file, because Windows doesn't allow
me to attach a file named `.emacs-history'. But trying to load that copy,
`emacs-history', also raises the same error.
However, something weird is going on. If the file is in c:/ when I try to load
it, then the error is raised. If the file is in c:/mydir/ when I try to load it,
then it loads with no error. I do not understand this at all. Exactly the same
file, different behavior. And it doesn't matter whether I make the file copy
using Emacs C-x C-w or using Windows copy+paste.
Dunno if simply attaching the file will enable you to reproduce
the bug - hope so.

It does, but I prefer not to call safe_to_load_p at all in that case.
I've installed a slightly different fix, see below.
(There's another, possibly similar bug: load-file fails for
C:/the-file.el.gz because jka-compr signals a wrong type argument
error. But that problem existed with the original Fload as well. I
will file a separate bug and see what I can find there.)
