This issue was fixed 6 months ago. Unfortunately it was after SaxonC 12.5 was released.
The fix was in the XdmNode.cpp file to avoid caching the parent node. See fix below:
XdmNode *XdmNode::getParent() {
int64_t nodeRef =
getParentForXdmNode(SaxonProcessor::sxn_environ->thread, (void *)value);
if (nodeRef > SXN_UNSET) {
return new XdmNode(nullptr, nodeRef, UNKNOWN);
}
return nullptr;
}
