Volker Hilsheimer f0049873d2 QMenu: don't crash when nested tear-off menus are closed ... QMenu's causedStack maintains a list of menus on the way to the menu, and might contain nullptr if one of the entries was a tear-off menu that got closed (and thus destroyed, due to DeleteOnClose). If the entry we get from the stack is nullptr, fall back to the passed- in parent widget pointer, and test for nullptr before accessing. Add a test case that crashes without the fix. Fixes: QTBUG-112217 Pick-to: 6.6 6.5 6.2 Change-Id: I958182db47c3cc8733e1780f7efef43881ffae11 Reviewed-by: Axel Spoerl <axel.spoerl@qt.io>		2023-06-09 00:08:36 +02:00
