Hello.
I can't reproject data from a Polar Stereographic projection (EPSG:3996) to a
geographic projection (EPSG:4326) correctly using ogr2ogr. Command:
ogr2ogr -t_srs EPSG:4326 -wrapdateline polys_4326.shp polys.shp
ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed
linestring
ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed
linestring
ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed
linestring
ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed

ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed
linestring
ERROR 1: IllegalArgumentException: Points of LinearRing do not form a closed
linestring
As a result some polygons are broken and also some polygons appears with
artifacts.
The data used and the result (58 MB):

.
How to reproject from a projection naturally crossing the anti-meridian to a
geographic CRS without any errors using ogr2ogr?
