Description

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

— the actual query that crashed — teh above is a distilled subset but there may be more monsters lurking in this query

SELECT ST_Contains(foo1.the_geom, foo2.the_geom) 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_MakePointM(i,j,m),4326),ST_SetSRID(ST_MakePointM(j,i,m),4326))  As the_geom
		FROM generate_series(-10,50,10) As i
			CROSS JOIN generate_series(50,70, 20) As j
			CROSS JOIN generate_series(1,2) As m
			WHERE NOT(i = j)
			ORDER BY i, j, m, i*j*m)) 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
