In PDQ-R 5.0, if a pdq::node has one name string in say, CreateNode(), but is referenced with another name string, say in SetDemand(), R 2.8.1 crashes. Not sure what happens in PDQ under the covers. That it crashes R is a bit uncool.
This could happen as a consequence of editing string names manually or adding other nodes and missing an instance.
