When I add the following line into my code, I get memory corruption error:

pcl::KdTreeFLANNpcl::PointXYZ kdtree;

In fact i'm subscribing to "/rtabmap/cloud_map" (using turtlebot RTAB-map) and do some processes. All the processes works well except when I add that line of KdTreeFLANN the program crashes.

I appreciate if anyone helps me. Thanks.
