Description
With certain slope configurations r.flow produces really strange output.
g.region n=200 s=0 e=200 w=0 res=1 r.mapcalc expression="sincos=sin(row()*5)*cos(col()*5)" r.flow -u elevation=sincos flowlength=flow_path
There is an old report of potentially incorrect array access, but no idea if it might be related: #1311

Notice horizontal dark blue lines - they shouldn't be there as surface is smooth in all directions from peaks to pits
