Subject: bug#44850: 27.1; Emacs crash in font handling with font-backend ns
Date: Tue, 24 Nov 2020 19:09:55 +0100 [thread overview]
Message-ID: <24509.19571.558312.286528@cochabamba.vanoostrum.org> (raw)
Emacs 27 crashes with the following init.el file:
(setq default-frame-alist
'((ns-appearance . darkgray)
(tool-bar-lines . 0)
(width . 100)
(top . 1)
(fullscreen . fullheight)
(modeline . t)
(mouse-color . "black")
(background-mode . light)
(menu-bar-lines . 1)
(cursor-color . "darkblue")
(background-color . "White")
(foreground-color . "Black")
(font . "-apple-Monaco-medium-normal-normal-*-12-*-*-*-m-0-iso10646-1")
(fontsize . 12)
(font-backend ns)
(left-fringe)
(right-fringe)))
I have been using this construction for years, but recently it caused
emacs to crash. I recently switched over to Emacs 27.1.1 after having
used an older Emacs 27 version for months.
The offending line is '(font-backend ns)', without this line there is no
crash.
Also if I start Emacs with -Q and eval this expression directly or load
.init.el there is no problem, only when it is used in the init file.
I read somewhere that font-backend 'ns' is deprecated, but Emacs
shouldn't crash. If this font-backend is wrong it should give en error
message.
As this is the distributed Emacs from
https://emacsformacosx.com/emacs-builds/Emacs-27.1-1-universal.dmg there
is no symbol table information
