Error, which causes the process to die

[kubs0ne]

Hello, I tried to initialize the localization node from your repository. I added a pcl pointcloud and the node visualizes it correctly in rviz. However, when I play my recorded bag file, the process dies. Right before dying it says:

terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

What could be the source of the problem?

Regards, Kuba
