GPU ndt _mapping hangs

edit

Hello, I am trying to use autoware ndt mapping with GPU (PCL_ANH_GPU = 2) but the mapping hands when 300 messages have been processed and that's all nothing more. No error message whatsoever.

But when I run any other mode it goes without a problem.

What could it be ? Or do you know any better way to generate a map out of lidar pointclouds ?

Thanks !

Here is the last output of ndt_matching :
