I tried this earlier today and to my surprise got a segfault. It still
needs an update from the sites lib to the vector lib. I used the
start_rast= option last week without any problems.

work around: (for a small number of starting points)
  COORDS=`v.out.ascii | cut -f1,2 -d'|' | tr '\n' ','`
  r.cost coordinate=$COORDS
