Hi all,

I'm converting large historical vector maps with ogr2ogr, using -gcp and 
-tps to rubbersheet the polygons with control points. Works fine up to 
about a thousand control points, each in the form of "-gcp fromx fromy 
tox toy". After that, the converted map becomes erratic. Is this a bug?

BTW, I am using gdal 2.1.0
