Description

When a circular string closes on itself to form a circle, the bounding box calculation does not return the right result. 

select 'CIRCULARSTRING(10 2,12 2,14 2)'::geometry && 'POLYGON((0 0,0 20,20 20,20 0,0 0))'::geometry;

I used the wrong words. The problem isn't closed circular strings, it's ones that aren't actually curves, that describe straight lines, so the three components are co-linear. The example is still correct.
