There is a core dump in r.to.vect when run over DCELL rasters.  Segfault originates at this line:

#0  extract_areas () at areas.c:283
283           v_list[col]->node = h_ptr->node = 1;

I think that in r.to.vect there should be an error message on trying to run it on a raster other than of CELL type.
