[Message part 3 (text/plain, inline)]

Newest Emacs (and 25.3) crashes for me. Unfortunately I can only 
reproduce this using newest versions of Ivy and yasnippet packages.

Emacs first crashed for me on 25.3, when I was calling 
`yas-expand-snippet` inside `save-restriction` form inside `ivy-read`. I 
wrote this form to try to reproduce this:

(progn
  (package-initialize)
  (require 'yasnippet)
  (require 'ivy)

  (yas-reload-all)

  (switch-to-buffer "*scratch*")
  (lisp-interaction-mode)
  (yas-minor-mode-on)

  (let ((templates (mapcar #'yas--template-key
                           (yas--all-templates 
(yas--get-snippet-tables)))))
    (defun update-fn ()
      (with-current-buffer "*scratch*"
        (save-restriction
          (narrow-to-region 3 3)
          (insert " " (ivy-state-current ivy-last))
          (yas-expand)
          (mapc #'yas-abort-snippet (yas-active-snippets)))
        (redisplay)))
    (let ((buffer-undo-list t))
      (while t
        (erase-buffer)
        (insert "aaaaaa")
        (redisplay)
        (sit-for 0.1)
        (run-with-timer
         0.01 nil (lambda ()
                    (dotimes (_ (% (random) 15))
                      (execute-kbd-macro "\C-n")
                      (sit-for 0.05)
                      (redisplay)
                      (when (zerop (% (random) 4))
                        (execute-kbd-macro "\C-p")
                        (sit-for 0.05)
                        (redisplay)))
                    (sit-for 0.1)
                    (redisplay)
                    (abort-recursive-edit)))
        (catch 'exit
          (condition-case err
              (ivy-read "foo: " templates
                        :update-fn #'update-fn)
            (quit)))))))


Steps to reproduce:

1. Install newest ivy, yasnippet and yasnippet-snippets

2. Run emacs -Q

3. Eval form above

4. Typically emacs crashes after about 1-2 minutes

Thanks, I installed that along with the attached minor refactoring so 
that the bugfix is in just one place. Closing the bug.

I assume that this fix should not be backported into the emacs-26 
branch, as the bug is in Emacs 25.
