Subject: bug#70124: 29.3.50; Crash via indirect buffers
Date: Mon, 01 Apr 2024 12:54:20 +0200	[thread overview]
Message-ID: <12427969.O9o76ZdvQC@gabor> (raw)

Hi,

After building Emacs from source, I have added the following file
to the build directory:

File ./bug-indirect-crash.el

;;; bug-indirect-crash.el --- Crash via indirect buffer  -*- 
lexical-binding: t; coding: utf-8; -*-

;;; Commentary:
;; Crash Emacs by stupid use of indirect buffers.

;;; Code:
(let (buffer)
  (with-temp-buffer
    (with-current-buffer
	(setq buffer
	      (make-indirect-buffer
	       (current-buffer)
	       (generate-new-buffer-name "indirect")))
      (setq-local kill-buffer-query-functions (list #'ignore))))
  (with-demoted-errors "Error: %S" (set-buffer buffer))
  (message "Current buffer: %s" (current-buffer))
  (insert ?A))
;;; bug-indirect-crash.el ends here.

End of file./bug-indirect-crash.el

Below is the command I have run Emacs and the output of the 
command:

$ src/emacs -Q --batch -l ./bug-indirect-crash.el 
Error: (error "Marker does not point anywhere")
Current buffer: indirect
Fatal error 11: Segmentation fault


I find the error about the marker weird, have no idea which marker 
it
is.
I expect an error like "Selecting deleted buffer" instead.
I also find the second line strange:
(seemingly an indirect buffer is current whose base buffer is 
killed).
