I'm getting the error below compiling a single tile with the following command: java -Xmx2500m -ea -jar mkgmap.jar --output-dir=./tmp --bounds=bounds.zip --precomp-sea=sea.zip --max-jobs --route --latin1 --code-page=1252 --index --housenumbers --style=truck 55139114.o5m java.lang.AssertionError at uk.me.parabola.imgfmt.app.net.RoadIndex.write(RoadIndex.java:45) at uk.me.parabola.imgfmt.app.net.RoadDef.writeLevelDivs(RoadDef.java:361) at uk.me.parabola.imgfmt.app.net.RoadDef.writeNet1(RoadDef.java:230) at uk.me.parabola.imgfmt.app.net.NETFile.write(NETFile.java:66) at uk.me.parabola.mkgmap.build.MapBuilder.makeMap(MapBuilder.java:263) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:107) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:69) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:263) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:259) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Removing --housenumbers tile compiles fine. What is causing the error is the absence of the following rule in lines file: # Mop up any unrecognised highway types highway=* & area!=yes [0x07 road_class=0 road_speed=0 resolution 23] Input data: http://alternativaslibres.org/files/tmp/55139114.o5m
