Description
The following code snippet crashes the process, it was working in Qt 5.9:
import QtQuick 2.0 Item { anchors.horizontalCenter: null }
With the following warning:
Invalid property assignment: unsupported type "QQuickAnchorLine" - Assigning null to incompatible properties in QML is deprecated. This will become a compile error in future versions of Qt.
While the warning is useful to fix the issue, it shouldn't crash.
