ST_DFullyWithin EMPTY crash with real

[robe]

I haven't isolated which one is at fault here. Doesn't seem to be POLYGON EMPTY this time.

SELECT ST_DFullyWithin(foo1.the_geom, foo2.the_geom, 100) As result, ST_AsText(foo1.the_geom) As ref1_geom, ST_AsText(foo2.the_geom) As ref2_geom
	FROM ((SELECT ST_MakeLine(ST_SetSRID(ST_Point(i,j),4326),ST_SetSRID(ST_Point(j,i),4326))  As the_geom
		FROM (SELECT a*1.11111111 FROM generate_series(-10,50,10) As a) As i(i)
			CROSS JOIN generate_series(40,70, 15) As j
			WHERE NOT(i = j)
			ORDER BY i, i*j)) As foo1 CROSS JOIN ((SELECT ST_GeomFromText('GEOMETRYCOLLECTION EMPTY',4326) As the_geom
			UNION ALL SELECT ST_GeomFromText('POLYGON EMPTY',4326) As the_geom
			UNION ALL 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 foo2 LIMIT 2;

— here is a distilled one if you need an example

SELECT 
ST_DFullyWithin(ST_GeomFromText('LINESTRING(-10 50,50 -10)',4326), ST_GeomFromText('POLYGON EMPTY',4326),5);
