I was testing my new routines (BoundaryPreparer with QuadTree) with all european bnd files. That crashed at some point. While debugging the code with a smaller
input in --createboundsfile  I got errors for the previously produced wrong bnd files.

The new BoundaryPreparer is really a difficult to code. I had to sort out where my algorithm was wrong and where the OSM data contains errors.
It's hard to say when results are only 99.9% identical to the trunk, but I am still optimistic.

Okay, I've learned that the hard way ;-)
