Dear all CGAL users,

I've a weird output from CGAL Straight Skeleton. I attached my output and the simple code to regenerate the output. My OS is Ubuntu 12.10 32-bit and I'm using CGAL 4.1. Could you please check the output? Is this a bug or am I doing something wrong?

In my analysis, I checked the approximation of the exact numbers to double by printing the intervals using CGAL::to_interval() for the skeleton vertices and there seems to be an anomaly for the point S3 (see the figures). The interval is given as:  [(650950.772473049, 650961.1943390622) (6861561.907245005, 6861566.64668196)] for that point. I think this is the source of the error. Is there a method for narrowing down the interval? 

Thank you for your time and considerations.

Best wishes
