The segfault is solved now (backported to 6.4.svn).

Still no faces any more... possibly unrelated?


The last one with sampling might be v.drape:
GRASS 6.4.svn (nc_spm_07):~/grass64 > g.region vect=roadsmajor
GRASS 6.4.svn (nc_spm_07):~/grass64 > v.drape roadsmajor out=roads_3d
rast=elevation

WARNING: Current region does not include the entire input vector map
         <roadsmajor>
WARNING: Elevation raster map <elevation> does not cover the entire area of
         the input vector map <roadsmajor>.
...

The first warning is surprising given the g.region command.
In the code there are also snippets like
                    estimated_elevation = scale * G_get_raster_sample(fdrast,

Help kindly appreciated...
