Since you use 6.3 there is some confusion which has been fixed in 6.4 and later. A minute ago I have backported the correction for numbering of terrain classification which is correctly as follows: TERRAIN = 1 EDGE = 2 UNKNOWN = 3 (see also http://grass.osgeo.org/grass64/manuals/html64_user/v.lidar.edgedetection.html ) > The next step is v.lidar.growing.

Would you mind to update to 6.4? We have made a couple of fixes since 6.3. If the problem persists, we could check it.
