Description

It seems that v.distance has a memory leak when run in LatLong? locations (version from today):

GRASS 6.3.svn (latlong_sphere):~ > CMD="v.distance -p -a coordinate_all_flocks_map to=coordinate_all_flocks_map upload=dist col=distance"
GRASS 6.3.svn (latlong_sphere):~ > valgrind --tool=memcheck --leak-check=yes --show-reachable=yes  $CMD --o
