Zorba crashes with getReference

[Federico Cavalieri]

The following query sometimes causes Zorba to crash:

import module namespace ddl = "http://www.zorba-xquery.com/modules/store/dynamic/collections/ddl";
import module namespace dml = "http://www.zorba-xquery.com/modules/store/dynamic/collections/dml";
import module namespace ref = "http://www.zorba-xquery.com/modules/node-reference";

ddl:create(xs:QName("ddl:coll"));
dml:insert-nodes-last(xs:QName("ddl:coll"),element {"bb"}{text {"aa"}});
ref:node-reference(dml:collection(xs:QName("ddl:coll")))

This is caused by the following cast:
const OrdPathNode* n = static_cast<const OrdPathNode*>(node);
which is not correct when node is a TextNode
