Hi Gerd I think you patch is the best solution. I was worried that it would interfere with the subdiv/area sizing rules when --order-by, which does allow very slightly oversized polgons, but these are never big enough to cause the next level down to exceed MAX_DIVISION_SIZE.

Hi Gerd
OK - I get the problem now, it was --order-by that stopped it happening. I think this oversize polygon should have been handled by MapArea and the maxSize/maxWidth/maxHeight limits and I'm now trying to work out why it isn't.

Hi Ticker,
I got this with trunk and no options, just -ea is important.

Hi Gerd
Just tried this on my low-res build without your patch and don't get a problem, but might be because of different options or pending ShapeSplitter changes.
What options are you using? I'll disable my other changes and try again

I've not looked at all the details, but the polygon overlaps the inital area extremely. The attached patch fixes the problem but I have not tested any side effects.
