[geos-devel] truncated buffer result

Hello,

I probably found a tiny issue in the buffer computation on a POYGON shape.

Using Mapserver geos implementation, I fell on a curious behaviour of
the buffer compuation (see attached image).
To reproduce the bug, I tried a similar request in PostGIS, and
obtained the same result. So I suppose this is a GEOS library issue.

psql -d database -c "SELECT
astext(buffer(geometryfromtext('POLYGON((663194 796327,663281
1796368,663226 1796300,663194 1796327.1,663194 1796327))'), 50));"

Do I have to fill in a bug ?

Regards

Pierre GIRAUD
