Subject: [geometry] snapshot of the future geometry 1.56 release

Hi Barend,

Sorry to bother you again. I am facing quite a large amount of crashes with either union_, or difference (and possibly others) when I try them on my large datasets (many hundred thousand polygons processed in various ways, I am actually porting existing working code from GPC to boost/Geometry). Most of what I see have to do with numerical robustness (e.g. computing the difference between two polygons that merely cover each other).
The ported code is expected to become production code by the end of the semester and it's not going to happen with version 1.54.
Since you told me a lot of work has been done about it in the future 1.56 release of boost::geometry, I was wondering if I could somehow try it (I believe I should download from to see how stable it has become regarding numerical robustness. The good thing would be that I could focus on reporting relevant crash cases and not the ones that are already fixed in your dev branch.

What do you think? Is the link I found the right one for that matter?

Thanks for your time.
