           Summary: Defend against stack overflow in
                    GraphicsLayerCA::recursiveCommitChanges
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

It looks like GraphicsLayerCA::recursiveCommitChanges can cause a stack overflow in some configurations.  We already have CommitState::treeDepth, which we use to avoid creating deep CALayer trees, so we should be able to stop the recursion at the same level.
