Subject: bug#26440: seq-mapn fails with circular sequence
Date: Tue, 11 Apr 2017 08:12:40 -0000 [thread overview]
Message-ID: <f2e98367f212ad432bfc4fe8ac541e1a.squirrel@cloud103.planethippo.com> (raw)
On Emacs-25 circular structures cause seq-mapn not to terminate
although the documentation suggest that they should.
Consider:
(defvar l '(a c d))
(setq l (nconc l l))
(seq-mapn #'cons l '(1))
This should return '((a . 1)) but actually does not terminate.
The problem is caused by call to seq-into which includes:
(append sequence nil)
The problem does exist on trunk which does this instead:
(if (listp sequence)
sequence
(append sequence nil)))
