Re: POINT_CLOUD_REGISTER_POINT_STRUCT Alignment on 32bit machines

David Lu!!
Hey PCLers,

I'm working on a bug with the ROS Navigation Stack. One of the
planners publishes a custom point cloud as defined here:
https://github.com/ros-planning/navigation/blob/hydro-devel/base_local_planner/include/base_local_planner/map_grid_cost_point.h

That's mostly been working fine, except a few people are running into
errors on 32 bit machines.
https://github.com/ros-planning/navigation/issues/135

Basically, I'm way out of my league here PCL-wise, and would
appreciate any pointers you had on how best to create the new struct
type.

Thanks,
David!!

Thanks for the heads up David. I just commented on the issue. This is a well known problem with vectorization, and Eigen structures that are to be aligned.

Best,
Radu.
