Your question is not about WebKit development, so it should be
directed to webkit-help mailing list. I've answered below, but please
choose a correct e-mail list in the future.
Please note that linking directly to WebCore is most definitely
unsupported and extremely fragile. One should always be using platform-
specific WebKit APIs.

The XPathResult object is destroyed at this point, so the rest of the
code operates on freed memory. One needs to keep the reference in
RefPtr. Also, you don't need dynamic_cast when downcasting - and we
build WebCore with RTTI disabled anyway.
RefPtr<WebCore::XPathResult> xpr = doc->evaluate(query, doc, 0,
WebCore::XPathResult::UNORDERED_NODE_ITERATOR_TYPE, NULL, ec);
