Crash while using VGICP

[jediofgever]

Hi,
When I use VGICP as a registration method,
after some time it crashes with the error below.

The append method of AdditiveGaussianVoxel seems to be the root of the problem.

Note that I am doing ICP SLAM, so the target cloud is being expanded, could the cause be that the size of the target cloud just hits a limit ?, because VGICP_CUDA, seems to do much better?

Thank you for your help
