[gdal-dev] Error in gdalwarp

[Paolo Cavallini]

Hi all,
I'm running gdalwarp on data from

https://github.com/qgis/QGIS-Training-Data/tree/master/training_manual_data/processing/iterative

as

gdalwarp -ot Float32 -q -of GTiff -cutline watersheds.shp -co
COMPRESS=DEFLATE -co PREDICTOR=1 -co ZLEVEL=6 -wo OPTIMIZE_SIZE=TRUE
dem25.tif OUTPUT.tif

and I get

GDAL command output:
Warning 1: Self-intersection at or near point 583.00000000000182 326
ERROR 1: Cutline is not valid after transformation

Previously the same command was running fine. I also checked geom
validity of the vector, and I coud not spot any error.

Is there an explanation?

GDAL 2.1.1+dfsg-5 on Debian sid.

All the best, and thanks.
