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).

Thanks. This is already fixed on the master branch (which will
eventually become Emacs 30), where I get:
emacs -Q --batch -l d:/usr/eli/data/bug-indirect-crash.el
Unable to kill buffer whose indirect buffer `indirect' cannot be killed
(Btw, even on the emacs-29 branch I don't see a crash, I see an error:
emacs -Q --batch -l d:/usr/eli/data /bug-indirect-crash.el
Error: (error "Marker does not point anywhere")
Current buffer: indirect
But that could be system-dependent.)
So I'm closing this bug as already solved.
