I created a network in the nc_08 demo data set from streets_wake and highschools extracted from schools_wake. When I ran v.net.steiner, I got the following error: {{{ (Sat Oct 6 23:39:56 2012) v.net.steiner input=hs_net_g6@spatialtech2012 output=hs_steiner_g6 tcats=4-164 Number of terminals: 21 Number of Steiner points set to 19 v.net.steiner(65199) malloc: *** mmap(size=233472) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Current region rows: 1350, cols: 1500 ERROR: G_malloc: unable to allocate 233168 bytes of memory at main.c:475 }}} It is broken in trunk (GRASS 7) too, but there is no error in GRASS 7. It just silently fails. v.net.spanning tree seems to be working incorrectly too. It largely reproduces the original network rather than finding a minimum set of connections between nodes.
