[postgis-users] GEOS Intersection() threw an error! Again

[Pierre viallet]

Hi Guy,
I know that i'm not the only one who have TopologyException probelm.
But the folowing exemple was running well in previous version (before geos 2.1.4) and return POINT(0.1,0.1) :

select
astext(intersection(geomfromtext('POLYGON ((0 0, 0 0.5, 0.1 0.5, 0.1 0.1, 0 0))', 27582), 
geomfromtext('POLYGON ((0.5 0, 0.1 0, 0.1 0.1, 0.5 0.5, 0.5 0))', 27582)))


I've chechek the validity of the two geom, and i try also

select  
astext(intersection(ForceRHR(geomfromtext('POLYGON ((0 0, 0 0.5, 0.1 0.5, 0.1 0.1, 0 0))', 27582)), 
ForceRHR(geomfromtext('POLYGON ((0.5 0, 0.1 0, 0.1 0.1, 0.5 0.5, 0.5 0))', 27582))))

Is there a way to work around this pb ? 
Does news geos 3.0.0 rc1 and the new binaryOp solve this ?

Regards,
Pierre
