 Using barin input produce a segmentation fault also if the map has got
 only 1/0 values (no null data).

 This is how to replicate the problem:

 {{{
 g.region rast=elevation.10m
 v.to.rast input=streams at PERMANENT output=streamTest use=val type=line
 layer=1 value=1 rows=4096
 r.null map=streamTest null=0
 r.report units=me map=streamTest | grep "no data"
 r.flow elevin=elevation.10m barin=streamTest skip=37 bound=9432
 flout=testvector lgout=testraster
 }}}

 Notice that without the barin option, the process works fine.
