Subject: bug#31146: 27.0.50; ielm via cl-prin1 infloops when printing circular object
Date: Fri, 13 Apr 2018 15:00:24 +0100 [thread overview]
Message-ID: <87in8v435z.fsf@tcd.ie> (raw)
(This is a repeat of a recipe I sent to bug#18012 as a separate report.)
The following change:
81b5131e11: 2018-01-15 17:04:05 -0500
* lisp/ielm.el (ielm-eval-input): Use cl-print.
https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=81b5131e11fa96d32a1718c6e2ebf40994d7d281
now results in the following behaviour:
1. emacs -Q
2. M-x ielm RET
3. (let ((l (make-list 2 0)))
(nconc l (cdr l)))
4. C-m
=> infloop
5. C-g
=> *** IELM Error *** Quit during pretty-printing
Evaluating (4) in *scratch* via C-j, by contrast, inserts (0 0 . #1)
without inflooping, presumably because pp is used instead of cl-prin1.
