I'm experiencing Segmentation Faults related to setting font faces
for
newly created frames. The same problem exists with Emacs-26.3.
I'm using the following minimal init.el file:
---8<----------------
defun ah/setup-gui-frame (frame)
(custom-theme-set-faces
'user
`(org-document-title ((t (:font "Garamond" :height
160))))
)
)
(add-hook 'after-make-frame-functions
(lambda (frame)
(when (display-graphic-p frame)
(ah/setup-gui-frame frame))))
(add-hook 'org-mode-hook 'variable-pitch-mode)
(add-to-list 'default-frame-alist '(font-backend . "xft"))
---8<----------------
Now, when I start Emacs and open an org-mode file, the document
title is
not displayed in Garamond, but in the system's default sans-serif
font.
When I now open a new frame with =C-x 5 2=, the org-mode file in
both
the new and the old frame are displayed in Garamond.
So far this is the behavior I expect.
I can now open new frames with =C-x 5 2=, but at some point (after
1--4
additional frames), Emacs quits with a segmentation fault.
The same happens when I'm using any other font that's installed on
my
system.
