Description
Hi,
I am using the PCL with ROS and I am trying to compute the OUR-CVFH descriptors on a clustered cloud. But every time I get the following error:
/usr/include/eigen3/Eigen/src/Core/DenseCoeffsBase.h:378: Eigen::DenseCoeffsBase<Derived, 1>::Scalar& Eigen::DenseCoeffsBase<Derived, 1>::operator[](Eigen::DenseCoeffsBase<Derived, 1>::Index) [with Derived = Eigen::Matrix<float, -1, 1>; Eigen::DenseCoeffsBase<Derived, 1>::Scalar = float; Eigen::DenseCoeffsBase<Derived, 1>::Index = long int]: Assertion `index >= 0 && index < size()' failed.
Reading online I think that this bus was fixed. Do I have to update my PCL in ROS?
Thank you.
Marco

Research direction
Start with the reported Eigen assertion in Eigen/src/Core/DenseCoeffsBase.h and the OUR-CVFH computation on the clustered cloud. Reproduce the failure with the PCL and ROS versions in use, then compare against the claimed fix. Done means identifying the failing input or version-specific cause and confirming the correction with a reproducible test.
