-Subject: [PATCH] Don't notify when unzooming windows from window_destroy()
+commit 6c0067c10360880334afa50815b880d04edcbf42
+Author: Nicholas Marriott <nicholas.marriott@gmail.com>
+Date: Thu Mar 21 11:30:42 2024 +0000
-Since commit 36e1ac65560, window_destroy() calls window_unzoom()
-but the latter emits a 'window-layout-changed' notification with
-the window which is about to be freed. This results in the
-callback later dereferencing a freed window, or a double-free.
+ Do not notify window-layout-changed if the window is about to be
+ destroyed (since it may have been freed by the time the notify happens),
+ from Romain Francoise in GitHub issue 3860.
-Closes: #3857.
