Re: [mkgmap-dev] [PATCH] make gps report correct exit when routing through roundabouts

The good news is that I *"think"* I have found the data that causes the problem. Call me sad if you want but I had a spare hour (not) so using osmosis I started splitting the tile giving the error into 4 quarters. I would run each of these and see if there were errors. I then split the quarter with errors and repeated the process until I was left with the attached file. In the bottom left quarter is a tiny roundabout. If you just move the north node northwards and the south road southwards a couple of feet then the tile runs without errors.

Nicely tracked down. The northmost and the eastmost points on that roundabout are about 5m apart and routing nodes have to be more than 5.4m apart. ..Steve
