           Summary: Leak in WebCore::SVGFontElement::create
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://crbug.com/120453
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bashi at chromium.org
                CC: zimmermann at kde.org, jschuh at chromium.org


See the stacktrace at http://crbug.com/120453.

r76990 introduced RefPtrs to hold SVGFontElement and looks like it is the cause of the leak. I checked removing RefPtrs fixed the leak and svg/custom/use-multiple-on-nested-disallowed-font.html passed successfully (DRT didn't crash). I think zimmermann's recent changes (e.g. r109333) disallow invalid svg contents like the test and the test is no longer effective.

jschuh@, zimmermann@, Do you think it is safe to remove RefPtrs which were introduces by r76990?
