Re: [Virtuoso-users] ST_Intersects with complex shapes

[Hugh Williams]

Hi Raul, I note your Virtuoso build is a 07.20.3214 build from early 2016 , whereas the latest builds are 3219, available from: https://github.com/openlink/virtuoso-opensource thus I would suggest compiling and building from this latest archive and rerun the query to see if the problem persists ...
