 GRASS-7.0 r44543

 There are occasions that v.parallel can not create parallel lines to a
 line, v.parallel cycles forever.

 Attached please find a small raster r35.txt and vector v35.txt which has a
 line and a centroid. The following sequence of commands will create an
 infinite loop:

 r.in.ascii -i --overwrite input=r35.txt output=r35[[BR]]
 v.in.ascii --overwrite input=v35.txt output=v35 format=standard
 fs='space'[[BR]]
 v.parallel -b input=v35 layer=-1 output=v35b distance=10 side=both
 --overwrite
