Subject: 11.88.6; Running "Check" command crashes aspell.exe
Date: Sun, 07 Jun 2015 01:18:15 +0200

As per the title; running the "Spell" AUCTeX command causes aspell.exe
to crash. My aspell version is the following:

@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.7-20131207)

and I am running a 64-bit Windows 8.1 with MSYS2 (all binaries are
64-bit). Running `ispell-buffer', `ispell-region' and the likes manually
works well, so I am assuming the error lies within AUCTeX. Flyspell
works fine also.

After aspell crashes, Emacs freezes, and I have no idea where exactly to
look for errors.

Thank you for your time.

That's strange.  AUCTeX's Spell command simply calls `ispell-buffer' for
any buffer displaying a file belonging to the current document.  So if
`ispell-buffer' works, i.e., aspell doesn't crash, then I can't see why
it should crash for the Spell command.

When emacs is frozen, you can usually get it responsive again by typing
`C-g' possibly a few times.  And then you could check if you get some
more information.  How did you conclude that aspell is crashing in the
first place?  Has some error message been printed?  If so, that will
also be appended to the *Messages* buffer.  If would be helpful if you
could post the exact error message if there's one.

Hi,

Thanks a lot for getting back to me. I did some more testing, and the results are very odd. Contrary to what I said previously, M-x ispell-buffer does not work either under TeX-mode. There were no problems in *any* other modes I tested. For example,

open a TeX file -> TeX-mode (AUCTeX) gets loaded automatically -> M-x ispell-buffer causes aspell.exe to crash -> unfreeze Emacs using C-g and change to, say, text-mode by running M-x text-mode -> M-x ispell-buffer works fine
open a blank file -> M-x ispell-buffer works fine -> switch to TeX-mode by running M-x TeX-mode -> M-x ispell-buffer fails again
open the *Scratch* buffer -> M-x ispell-buffer works fine -> switch to TeX-mode -> same issue

The story is the same with flyspell-mode and other such commands; aspell.exe also crashes under TeX-mode.

My preferred encoding is set to UTF-8. Line endings seem to make no difference. Running M-x ispell-buffer on "unconventional" buffers, such as R console, dired, etc, works fine too.

There are no error messages in *Messages*, but Windows gives me the following: "An unhandled win32 exception occurred in aspell.exe [3608]."

The issue happens in empty buffers, too. `ispell-cmd-args' and `ispell-extra-args' are both nil.

Any ideas? I'm clueless.

Well, then that's not an AUCTeX issue at all so I'm closing the bug.
But anyway, I think the major differences between "normal" modes and
tex/latex modes is that with the latter, `ispell-parser' is set to 'tex
which causes spell-checking to ignore latex macros like \documentclass
or environment names.

For example, when you do

  M-: (let ((ispell-parser 'tex)) (ispell-buffer)) RET

in some text-mode buffer, do you also get the crash?  I guess so.  Then
it's probably an aspell on windows issue...

Bye,
Tassilo
