After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
For curves, ellipses, etc, PLANAR or PRESERVE_SHAPE options are recommended.
Export to a shapefile, which does not support true curves, or use the Densify tool.
