While working on deserialization of sensor_msgs/PointCloud2 to DataPoints I noticed that the function DataPoints::getEuclideanDim() can return very high values when the point cloud is empty. This happens due to unsigned type underflow.
I added a ternary expression that checks if the number of features is 0, and based on that returns 0 or the number of features minus 1.
