Description (last modified by )
I tested on 3.8.0 and works fine there (still have to test on 3.8.1) but definitely an issue on GEOS head.
SELECT ST_VoronoiLines('MULTIPOINT(-10 40,5 40,20 40,35 40,50 40,-10 55,5 55,20 55,35 55,50 55,-10 70,5 70,20 70,35 70,50 70)'::geometry, 20.1, 'POINT(-11.1111111 40)'::geometry)
