Subject: patch 9.2.0641: GTK4: crash in gui_mch_menu_hidden()
X-Git-Tag: v9.2.0641^0
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fb3208a5f6d143bd02b7aa34ddc44701b7b5eb0a;p=thirdparty%2Fvim.git

patch 9.2.0641: GTK4: crash in gui_mch_menu_hidden()

Problem:  GTK4: crash in gui_mch_menu_hidden()
Solution: Skip the sentinel like gui_mch_menu_grey() does
          (Yasuhiro Matsumoto).

Menu items use the (GtkWidget *)1 sentinel as their id, but
gui_mch_menu_hidden() only skipped NULL ids and passed the sentinel
to gtk_widget_get_visible(), causing a SEGV.

closes: #20523
