I now have a precise test case that makes Emacs totally hang on my
machine every time:
(1) With M-:, I evaluate the following forms in "emacs -Q":
(defmacro preserve-message (form)
`(let ((msg (current-message)))
,form
(message "%s" msg)))
(let ((n 0))
(while (< n 10)
(with-timeout (1 (setq n (1+ n)) (message "# timeouts: %s" n))
(condition-case err
(with-temp-buffer
(insert "test")
(preserve-message
(ispell-word nil t)))
(error (message "error: %s" err))))))
(2) In a separate terminal, I continuously kill the aspell process:
while true; do killall -9 aspell; sleep 0.1; done
(3) I wait until the timeout counter has reached 10, i.e., evaluation
of the second form above is finished, then I evaluate the forms:
(defun reactivate-flyspell ()
(unless (memq 'flyspell-post-command-hook post-command-hook)
(preserve-message
(flyspell-mode 1))))
(setq my-idle (run-with-idle-timer 0.1 t 'reactivate-flyspell))
(4) Then I enter and exit Gnus three times:
M-x gnus RET q y
M-x gnus RET q y
M-x gnus RET q y
all while aspell is constantly killed and restarted in the
background. Starting Gnus only once does not suffice.
(5) I kill the shell script, so aspell can now run interruptedly. I
enter and try to exit Gnus again:
M-x gnus RET q y
and Emacs hangs completely. I cannot interrupt it with C-g. The
backtrace follows.
This is with GNU Emacs 23.0.60.1 (i386-apple-darwin8.11.1, GTK+ Version
2.12.9) of 2008-06-29; I will try to reproduce it with different
machines later. You may have to adjust the sleep time in the shell
command to kill the aspell process not too often.
