ST_ClusterKMeans garden crash - not empty geometry safe

[robe]

SELECT ST_ClusterKMeans(foo1.the_geom, 3)OVER()  As result
							FROM ((SELECT ST_GeomFromText('POINT EMPTY',4326) As the_geom
			UNION ALL SELECT ST_GeomFromText('MULTIPOINT EMPTY',4326) As the_geom
			UNION ALL SELECT ST_GeomFromText('MULTIPOLYGON EMPTY',4326) As the_geom
			UNION ALL SELECT ST_GeomFromText('LINESTRING EMPTY',4326) As the_geom
			UNION ALL SELECT ST_GeomFromText('MULTILINESTRING EMPTY',4326) As the_geom ) ) As foo1 LIMIT 3;

Do this and server hits the sac.

Simplified also crashes

SELECT ST_ClusterKMeans(foo1.the_geom, 1)OVER()  As result
	FROM (SELECT ST_GeomFromText('POINT EMPTY',4326) As the_geom) As foo1;

No rush but just wondering pramsey if any update on this. At least to confirm you have the same issue?

Confirm it's still there for you? I did some changes in this area of problem and I'm not seeing it against turnk

okay didn't even think to scheck. Looks fine. I get this now.
