Recipe:
* Create file 'testautoload.el' in /home/whatever/test containing
--------------------
;;;###autoload
(defun testautoload-testfunc ())
;; Local variables:
;; generated-autoload-file: "foo.el"
;; End:
--------------------
* Now create autoload file using (all in one line)
emacs --batch -l autoload -f toggle-debug-on-error
--eval '(setq generated-autoload-file "/home/whatever/test/foo.el")'
-f batch-update-autoloads /home/whatever/test
You'll see:
...
Wrote /home/whatever/test/foo.el
Making generated-autoload-file local to *autoload-file* while let-bound!
Generating autoloads for testautoload.el...
Generating autoloads for testautoload.el...done
Saving file /home/void/test/foo.el...
Wrote /home/void/test/foo.el
(No changes need to be saved)
and the file foo.el will be generated (BTW, shouldn't the above
*autoload-file* better denote the actual file name?)
* Now simply call the above command again. You'll get:
Debugger entered--Lisp error: (wrong-type-argument listp "77d69bf537d61f438126776e130fef3d")
time-less-p("77d69bf537d61f438126776e130fef3d" (20161 36303))
update-directory-autoloads("/home/whatever/test")
apply(update-directory-autoloads "/home/whatever/test")
batch-update-autoloads()
[...]
This is due to the following autoload header in foo.el:
;;;### (autoloads (testautoload-testfunc) "testautoload" "testautoload.el"
;;;;;; "77d69bf537d61f438126776e130fef3d")
;;; Generated autoloads from testautoload.el
where the md5-looking hex-string is obviously not a time.

The problem only occurs when the buffer-local value of
generated-autoload-file points to the same file as the global value.
This should be fixed, but in the meantime you can work around it by
simply not setting the buffer-local value (because setting it to the
global value is at best a no-op).

I can confirm it is fixed; thank you!
You're right of course that those variables are a no-op, but they come
from the CEDET Emacs-merge and I'd like to keep them to make merging
easier.

I'm sorry, I first misread your statement in the sense that you fixed
the bug, and then performed the check on the wrong file... the bug is of
course still there.

Could you check if the (additional) patch below works as well?

Yes, it works as well.
I have related question, though: I also tried to work around this thing
by setting `enable-local-variables' to nil:
emacs --batch -l autoload -f toggle-debug-on-error
--eval '(setq generated-autoload-file "/home/whatever/test/foo.el")'
--eval '(setq enable-local-variables nil)'
-f batch-update-autoloads /home/whatever/test
However, this does not seem to work; the file-local variable is still
the one to which the autoloads are written to. Is this to be expected?

Yes: autoload.el let-binds enable-local-variables to :safe.
Maybe it should keep it at nil if the default is nil? If you think it
would be better, please make a new bug-report for it.
