double free or corruption (!prev)

[GuillaumeAnoufa]

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

Add this line after https://github.com/Livox-SDK/livox_free_space/blob/master/src/FreeSpace.cpp#L255

pVImg = NULL;

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.
