 Hi,

 In postgis try-ing a Buffer with this:

 select
     1 as id,
         ST_Buffer(ST_GeomFromText('MULTILINESTRING(
         (1676339.95971128 4847443.67952346,
         1676340.19 4847443.54,
         1676338.44 4847440.65,
         1676335.37 4847442.52,
         1676337.12 4847445.4,
         1676339.95971128 4847443.67952346)
 )'),1) as geom;

 I experience a Bug .
 The buffer build a Polygon with a strange secondary polygon near a vertex.

 The Geos used from Postgis 1.5.1 is Geos 3.2.0, so I try
 downloading the last Geos 3.2.2 compile and use it.
 But the bug is still here.

 I work with windows , postgis 1.5.1.
