infinite loop with specific values

[iperov]

now I checked in C++ your file, its dead loop

_bin_size = 16; Eigen::Vector3d ray_start(-668, -340, 77); Eigen::Vector3d ray_end(404, -64, -784);

[iperov]

its look like accumulating double-error result error in final 1 step.

@iperov hello， did you solve that？
