           Summary: Remove unnecessary (and problematic) copy-constructor
                    from LayoutUnit
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mstensho at opera.com


This copy constructor does what a default copy constructor would do, so it's not necessary. Furthermore, this copy constructor is the only reason why LayoutUnit becomes non-POD, and that triggers a gdb bug, making it impossible to do things like "print location()" when inside some RenderBlock, for instance. Gdb bug http://sourceware.org/bugzilla/show_bug.cgi?id=15154 reported on that.
