Summary0004367: Crash when DataTemplates contain circular references
Description

When a DataTemplate circular reference is indirect (DataTemplate.Outer -> DataTemplate.Inner -> DataTemplate.Outer) - see ContentControlCrash.xaml
When a DataTemplate contains an ItemsControl which references the current DataTemplate (DataTemplate.Outer -> ItemsControl ItemTemplate DataTemplate.Outer) - see ItemsControlCrash.xaml
