           Summary: ASSERTION FAILED: m_numNodeListCaches
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: danceoffwithyourpantsoff at gmail.com


var doc = document.implementation.createHTMLDocument('a');
Node's can cache nodelists in m_nodeLists.  They keep a counter on their
document, via document()->addNodeListCache and document()->removeNodeListCache.
 However, when a node is adopted between documents, nothing is done to keep
this balance.  On adoption, we should be clearing m_nodeLists and calling
document()->removeNodeListCache.


var b = document.createElement('b');
// Give it a node list cache on document
b.childNodes;

// Attach it to doc to update m_document
doc.adoptNode(b);
doc.body.appendChild(b);
doc.body.removeChild(b);

// GC here if you can, or reload the page to fire ~Node and cleanup m_nodeLists
