Details - Since ConfigParser inherits from ParameterTree its subtrees are ParameterTrees. In order to have compatibility the sub() method returns a ConfigParser obtained by a static cast from the base class ParameterTree.

Although this seems OK (the derived class has the same memory layout) it violates the strict aliasing rule.
