Once again, thanks for explaining the details. This morning I investigated 
the code that leads to the failure above and it indeed turned out to be my 
own mistake. I had not initialised a certain Point variable. When using a 
Point based on doubles this does goes unnoticed. The bug was thus already 
present in the other/original code.
