Unstable results from ST_Within

[strk]

This is pretty puzzling. Load attached dataset, then:

-- This query says none of the 3 polygons contain the point
=# select gid, ST_Within(
ST_GeomFromText('POINT (-115.04252 36.05137)', -1), the_geom
) from foo_reload;

-- This query says polygon 3 does contain the point
=# select gid, ST_Within(
ST_GeomFromText('POINT (-115.04252 36.05137)', -1), the_geom
) from foo_reload where gid = 3; 

Storing the point geometry into a table makes no difference. Geometry number 3 really contains the point. The other two don't.

I've tested this with PostgreSQL 8.4.3, PostGIS 2.0.0SVN and GEOS 3.3.0dev
