double free or corruption (!prev) #1

Open GuillaumeAnoufa opened 2 years ago

GuillaumeAnoufa commented 2 years ago

Hello,

I have tried to run this node with my lidar (Livox Avia) or with your test bag (data/demo.bag) and with both methods I receive an error 'double free or corruption (!prev)' after the first cloud callback.

My system is:

Ubuntu 20.04 ROS noetic pcl 1.10

Hi, I resoved above issue. Please add "return 0" at the end of the function int LivoxFreeSpace::GenerateFreeSpace(float* fPoint_In, int pointNum, std::vector & free_space). Best, Taehan.
