bug#38750: Segmentfault on Emacs 26.3

[c4droid]

* Phenomenon
GNU Emacs crashed with a segmentation fault by initializing with a font
change setting.
* Environment
  1. Linux Mint 19.2
  2. GNU Emacs 26.3 (Compiled from source)
* How to reproduce
  1. Use the specified .emacs.d (Latest commint 248995b)
     $ git clone --depth 1 https://github.com/hekinami/dotemacs ~/.emacs.d
  2. Run emacs to initialize .emacs.d
     $ emacs # Be waiting for the completation of packages installing patiently
  3. Create a file (Just because of a miss of the configuration)
     $ mkdir -p ~/.emacs.d/contents/organizer/fin
     $ touch ~/.emacs.d/contents/organizer/fin/fin.ledger
  4. Revise .emacs.d/settings.org
     From:
     #+BEGIN_SRC emacs-lisp
     (use-package all-the-icons
       :ensure t) ;; M-x all-the-icons-install-fonts
     #+END_SRC
     To:
     #+BEGIN_SRC emacs-lisp
     (use-package all-the-icons
       :ensure t
       :config
       (set-fontset-font t 'unicode (font-spec :family "all-the-icons") nil 
'append)
           (set-fontset-font t 'unicode (font-spec :family "file-icons") nil 
'append)
           (set-fontset-font t 'unicode (font-spec :family "Material Icons") 
nil 'append)
           (set-fontset-font t 'unicode (font-spec :family "github-octicons") 
nil 'append)
           (set-fontset-font t 'unicode (font-spec :family "FontAwesome") nil 
'append)
           (set-fontset-font t 'unicode (font-spec :family "Weather Icons") nil 
'append)) ;; M-x all-the-icons-install-fonts
     #+END_SRC
  5. Run emacs again, then the error occurs.
