Hi all,

I am getting incorrect results using bg::union_ with double precision.

The union of two slightly intersecting (~sharing an edge) rectangles r1 and
r2 covers the only one of both. 

The problem is very similar to the one described in the following unanswered
topic:

http://boost-geometry.203548.n3.nabble.com/Severe-precision-problems-with-unions-td3423635.html 

I am using x86_64, GCC 4.5.1 and boost::geometry 1.49. Switching to trunk
(boost::geometry and boost::math) does not solve the problem.

Regards, 

Vasiliy
