Yup - that is most likely the issue. Please notice that the point_cloud_perception_experimental stack is always a bit 
behind perception_pcl, so issues like this could arise. In theory, that's where we dump experimental code before it 
reaches stability and can be integrated into PCL.

If you found the package that includes eigen3, we could start fixing its code. Just let us know which one it is.


Cheers,
Radu.
