           Summary: False-positive over-release of WebView in
                    destroyWebViewAndOffscreenWindow() in
                    DumpRenderTree.mm

            Status: NEW
          Severity: Normal

The clang static analyzer complains that 'webView' is over-released in destroyWebViewAndOffscreenWindow() in DumpRenderTree.mm.

The current code retains 'webView' in createWebViewAndOffscreenWindow(), returns it, then assumes that [mainFrame webView] returns the exact same WebView in destroyWebViewAndOffscreenWindow().
