This intersection has a unexpected result in OpenSCAD 2011.06

```C
radius = 100;

intersection(){
circle(r=radius);
square([radius,-radius]);
}
```

some sort oft pattern i discovered here:
```
[ radius, radius] // works
[ radius,-radius] // fails
[-radius,-radius] // works
[-radius, radius] // fails
```
