Description
The attached example creates an inline component "Button" in a file called MyComponents.qml. This component derives from QQuickButton. When it's instantiated from Main.qml, it causes the application to hit an assert:
ASSERT: "_size < _alloc" in file qtdeclarative/src/qml/qml/ftw/qfinitestack_p.h, line 79
The stack trace indicates that this has to do with the "background" delegate of a QQuickControl being deferred until QQuickControl::componentComplete().
