[mkgmap-dev] r4809 crashes by buildung mdr

Tue Oct 26 10:07:29 BST 2021

Hi Gerd & Arndt

I've also failed to reproduce this.

I suspect the problem is relating to some slivers of regions/countries
around the main map area containing maybe 0/1 city and so it could be
very sensitive to the exact contents of the map.

I used the splitter on europe-latest.osm.pbf with
  --polygon-file=Speiche_NRWplus.poly to generate the tiles but this
will have a slightly different content to cutting with a different tool
(osmosis) @Arndt - how do you do this? and also the areas.list

It also might be sensitive to options like housenumbers, sea
generation, bounds, location-autofill, name-tag-list, add-pois-to-area,
etc. @Arndt - can I have you option list.

@Gerd - Now I have a set of .img files and the MDR, I'll try as you
suggest and see what is the structures are around these indices.
