            Bug ID: 225250
           Summary: Defend further against a PlatformCALayer's owner
                    becoming null in
                    PlatformCALayerCocoa::drawLayerContents.
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned@lists.webkit.org
          Reporter: heycam@apple.com
                CC: bfulgham@webkit.org, simon.fraser@apple.com,
                    thorton@apple.com, zalan@apple.com

At the end of PlatformCALayer::drawLayerContents, we null check layerContents for the \
platformCALayerShowRepaintCounter call but not the \
platformCALayerIncrementRepaintCount call.
