           Summary: Potential leak in JSSVGDynamicPODTypeWrapper
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org

JSSVGDynamicPODTypeWrapper inherits from RefCounted (via JSSVGPODTypeWrapper), but RefCounted will not call its virtual destructor. So, data members of JSSVGDynamicPODTypeWrapper will not be destructed in the normal course of RefCounted lifetime.

I think the original issue is that JSSVGPODTypeWrapper should not have inherited from RefCounted, and then someone fell into the trap of actually doing meaningful work in the destructor.
