    initial v4  
    66should likely read '''Position::RIGHT'''.

     8As shown in the test case, the problem is that for the given LINESTRING:

     17BufferParameters params;
     18params.setJoinStyle(BufferParameters::JOIN_MITRE);
     19params.setMitreLimit(5.57F); // somewhere between 5.5 and 5.6
     20params.setSingleSided(true);
     21BufferBuilder builder(params);

     23builder.bufferLineSingleSided(input, distance, false); // 0-vertex output
