Hello, I can not reproduce the issue on my ~AMD64 Gentoo system. GRASS versija: 7.1.svn GRASS SVN revision: 66489M Build date: 2015-10-14 Build platform: x86_64-unknown-linux-gnu
Try to install GRASS 7.1 nightly and report back if you still have problems with it. I don't see any recent changes to v.voronoi and valgrind also does not complain - will be hard to trace down if problem has not been solved in 7.1 by accident.
