[mkgmap-dev] Another AssertionError

Tue Sep 22 21:54:05 BST 2020

I get the error reproduced below when I combine osm and contour lines 
precompiled tiles for the map of all Asia. Command line used is:

java -Xmx27G -ea -jar mkgmap_trunk.jar --gmapi --max-jobs --index 
--latin1 --code-page=1252 --description="OSM-$MAPA-Topo"

--product-version=$VERSION --series-name="OSM-$MAPA-Topo"

I use the same command for many other maps, including big ones like 
Europe or North America without problems, only Asia fails. I can provide 
all input files if necessary, but they sum several GB.
