[gdal-dev] [ogr2ogr] Anti-meridian issue when reprojecting from a Polar Stereographic projection to a geographic CRS

[Andrey VI]

Hi Even,
 
thanks for the fix.
With ogr2ogr re-projection now works as expected, but when using gdal vector pipeline (reproject -d EPSG:4326) it  works without any changes . Is this correct?
