getChildNodes errors in Xalan 1.12

[Paul Kinnucan]

Hi,
 XalanNode.getChildNodes() triggers an error in Xalan 1.12 on Windows and 
Linux. All the other node navigation methods work fine, e.g.,

XalanNode *pDoc = 
static_cast<XalanNode*>(_LiaisonPtr->parseXMLStream(inputSource));
const XalanNode *pChild = pDoc->getFirstChild(); // works
const XalanNodeList *pList = pDoc->getChildNodes(); // Never returns. Triggers 
a std::exception of unknown cause.

I am able to simulate getChildNodes, using getFirstChild and getNextSibling.

Any idea what the problem is?

Paul
