All I know is I turned it into an EXCEPTION.
Was entering an infinite loop before.
A good start is catching the exception...
If you feel you could also file a ticket on trac.osgeo.org/geos
with a description of the issue and a link to the video.
It's intereting to see how to _obtain_ infinite values during
computation of the offset curve.
