Hello, After bug 26097 was fixed I started using emacs built from soruce from the master branch. There I encountered a but that only recently I traced back to 8275687bb908174b84021ee15ecd959733cecb9d with a git bisect. Here are some high level details: 1) I am using Spacemacs (https://github.com/sdwolf/spacemacs/tree/develop) with evil and helm. 2) I have linum active. 3) I press "M-x" which is bound to (helm-M-x). This opens helm and triggers something called "Auto Evilification". Somewhere in this process the following message is displayed: ``` Auto-evilification could not remap these functions in map ‘edebug-mode-map’: - ‘edebug-Go-nonstop-mode’ originally mapped on ‘G’ ``` This is a single string with multiple "\n" inside it that can be generated by the following code (extracted from Spacemacs): ``` (setq my-map-symbol 'edebug-mode-map) (setq my-pending-funcs '((edebug-Go-nonstop-mode . 71))) (message (concat (format (concat "Auto-evilification could not remap these " "functions in map `%s': \n") my-map-symbol) (mapconcat (lambda (x) (format " - `%s' originally mapped on `%s'" (car x) (single-key-description (cdr x)))) my-pending-funcs "\n"))) ``` 4) After the above message is displayed emacs freezes. 5) If i do a "pkill -USR2 emacs" I get a backtrace that looks like the attached file. I can not paste it because it contains some nulls (^@) and it gets truncated. 6) I did a git bisect and it led me to this commit: 8275687bb908174b84021ee15ecd959733cecb9d, the first attempt at fixing 26097, later edited by a749b55d8ee530797ccff693ad302541257d0415. 7) If I remove the "\n" from the message, making it a single line, the problem no longer appears. Also if I disable linum in the currently open buffer then there is no problem with the multi line message. Here is a reference to the github issue in which I, and a few more people discuss about this bug. I can provide a VM for you to ssh into and reproduce the bug with my setup. Just email me privately so I can give you the ssh details. Also let me know if you need any more details from me. I will try to answer as quickly as possible. Thank you, Codrut
