Description
Reported by user here: https://saxonica.plan.io/boards/4/topics/9826?r=9838#message-9838
The following C++ code snippet which attempts to use the XdmNode copy constructor is failing:
...
root = new XdmNode(*child);
delete child;
XdmNode **children = root->getChildren();
The problem is the internal reference in the object handle pool for child node object is shared in the new copy (i.e. root), but this gets destroyed by the call delete child and therefore will be garbage collected at some point in the GC cycle.
The only real workaround is to avoid using the copy constructor.
