Subject: bug#46407: 27.1; Hooks with permanent-local-hook are not cleared of lambdas
Date: Tue, 09 Feb 2021 22:38:49 +0100	[thread overview]
Message-ID: <87ft249b12.fsf@miha-pc> (raw)
In-Reply-To: <87im7182fn.fsf@miha-pc>

Also one more thing:

    (defvar some-hook nil)
    (add-hook 'some-hook #'some-fun nil t)
    (put 'some-fun 'permanent-local-hook t)

If we mark a function as permanent-local-hook only after adding it to a
hook, the hook symbol will not have its permanent-local property set to
'permanent-local-hook, so some-fun will not be kept on removal of local
variables.

This can be a real non-theoretical problem when adding an autoloaded
function to a hook.
