Under certain circumstances the third parameter(const NodePtr node) passed in the searchLevelExact method in file kdtree_index.h seems to be NULL, leading  to a crash. 

The method traverses the tree recursively. Unfortunately it isn't checked that a child is really existing before trying to visit it. The method only stops traversing if both childs aren't present. 

I'm not sure if a null pointer check is missing here or if it is a tree construction problem. Maybe a node should always have two children or none. In this case the method would be right.
