[mkgmap-dev] special case where splitting fails without a log message

Thu May 27 15:33:12 BST 2021

Hi Ticker,

with my current test environment the patch doesn't improve the result.
It reports some errors (the old code didn't always detect them) and eithers add or removes parts of the heavily merged shapes.

I've inspected one shape and found no obvious problem. No point is visited more then twice, but 167 points are visited twice. Let me know if you need the data.

Gerd
