Illegal memory access in gpu::octree #2103
Description
I detected an illegal memory access, in octree_builder.cu:246. I'm not sure how reproductible this is.
- The pcd file (just replace the extension if needed).
- No error is triggered in my system if the point cloud as 950 points instead of 951.
- Hardware: GeForce GTX 1060
- Driver: 384.90
- CUDA Version: 8.0
