[REG 5.6Beta-5.6.0] Access Violation in QQuickItem's dtor when used as a container with a layout

    XMLWordPrintable

Details

    Description

      When using a custom Window container with forwarded default property and a Text item in the contents of the container, QWindow's destructor crashes when deleting QQuickText.

      This works in 5.6.0 beta, but crashes on 5.6.0 RC in
      Qt5Quickd.dll!QQuickItem::~QQuickItem() @ qquickitem.cpp Line 2333

      Attached example to reproduce the crash. Use the debugger in a debug build.
