           Summary: Clear the external characters pointer of an
                    AtomicHTMLToken before the raw token is cleared.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: skyul at company100.net


AtomicHTMLToken keeps a pointer to the HTMLToken's buffer instead of copying the characters for performance. Clear the external characters pointer before the raw token is cleared to make sure that we won't have a dangling pointer.
