Subject: Avoid assertion violations in displaying under 'outline-minor-mode'
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=ff6448024b615932816bc24a8cd703c843cf1e91;p=emacs.git

Avoid assertion violations in displaying under 'outline-minor-mode'

* src/xdisp.c (init_from_display_pos): Initialize BYTEPOS
correctly, since 'init_iterator' no longer computes it from
CHARPOS as needed.  This fixes a change made on Mar 13, 2013.
(Bug#71194)

(cherry picked from commit 4f0121f8dbe2ca0ec8fe2831353f01782e5e6b9d)
