Subject: ispell
--text follows this line--

I invoke Emacs or, from a command line, emacs -Q. Then I load some
file text.tex and run ispell. Now, when I want to terminate ispell
before it has proved the whole text, I type the letter q.
The system then asks

Really kill ispell process? (y or n)

I type 'y' and now emacs hangs. I cannot terminate the program
by C-g, even when I type this repeatedly. I can terminate emacs only
with the Windows task manager.

I found that emacs hangs when the function ispell-kill-ispell
(in ispell.el) is called and when the command (delete-process  
ispell-process)
within this function is called.

I have installed Ispell 3.1.20

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
     `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
d:/Programme/emacs/etc/DEBUG for instructions.

Thank you for a detailed recipe.  Unfortunately, like Jason, I cannot
reproduce this on my machine: when I type `q' and answer `y' to the
above question, Emacs says that Ispell was killed and does not hang.

> I have installed Ispell 3.1.20

Where did you get this port of Ispell?  Can you please post everything
that this Ispell displays when you type "ispell -vv" at the Windows
command shell prompt?

This seems to be a Cygwin port of Ispell.  Cygwin ports are subtly
incompatible with native Windows executables such as the Windows port
of Emacs.  I suggest to install a different port of Ispell, e.g. from
this site:

I'm glad I was able to help you.

Thanks for working on this.

delete-process

[Ekkehard Krüger]

Hallo,

I have upgraded my emacs to Emacs 22.1.1 (i386-mingw-nt5.1.2600)
  of 2007-06-02 on RELEASE.

I believe that the function "delete-process"  now is undefined.
Therefore, emacs crashes whenever this function is called.
(For instance, when ispell is terminated by "Q".)

Thank you for the report, but I cannot reproduce this. delete-process is 
a built in function, so there is no way it cannot be defined, and an 
undefined function would not lead to a crash.

Can you reproduce the problem if you start Emacs from the command-line 
as "emacs -Q"?

What does C-h f RET delete-process RET give on your system?

How does "emacs crash"?  Please be more specific here.

Do you mean when you type `q' to "quit spelling session (Kills ispell
process)"?
