Comment 9 for bug 1437930

I know what is causing this bug.
Jean-pierre:

Considering this is the cause of the bug:
    // Number of segments to convert a circle to polygon
    // Boost polygon (at least v 1.54, v1.55 and previous) in very rare cases crashes
    // when using 16 segments to approximate a circle.
    // So using 18 segments is a workaround to try to avoid these crashes

Then in this line:
775 pad->BuildPadDrillShapePolygon( allLayerHoles, 0,
                                                    (int)(segcountLowQuality * segFactor) );

We need to make sure that the value is not 16, something like:
nrSeg = (int)(segcountLowQuality * segFactor);

if( nrSeg == 16 )
    nrSeg = 15;

:)
I will on holidays away from the computer to test and patch it, I appreciate if you can fix it for me!
