Note: the following error only happens using the index branch, if I use trunk it compiles fine. I continue here, because I get exactly the same error message, it is not related to missing --latin1 however: (for me it happens on several countries, though most go through fine. Smallest Geofabrik extract affected is slovakia, but also Germany, Bayern, Sachsen, and some others break due to this bug -- adding code-page=1252 in front of --latin1 doesn't help) c:\OpenMTBMap\maps>start /low /b /wait java -jar -Xms4000M -Xmx7000M c:\openmtbmap\mkgmap.jar --max-jobs=4 --generate-sea --latin1 "--style-file=c:\openmtbmap\new4" --nsis --index -- transparent --adjust-turn-headings --add-pois-to-areas --ignore-maxspeeds --reduce-point-density=3 --x-reduce-point-density-polygon=6 --link-pois-to-ways --precomp-sea=c:\openmtbmap\maps\sea --ignore- turn-restrictions --min-size-polygon=14 --remove-short-arcs=4 --description=openmtbmap_sk --show-profiles=0 --merge-lines --location-autofill=bounds,is_in,nearest --bounds=c:\openmtbmap\maps\bounds - -route --country-abbr=sk --country-name=slovakia --mapname=64090000 --family-id=6409 --product-id=1 --series-name=openmtbmap_slovakia_20.06.2012 --family-name=mtbmap_sk_20.06.2012 --tdbfile --overview -mapname=mapsetx --keep-going --area-name="slovakia_20.06.2012_openmtbmap.org" -c c:\openmtbmap\maps\template.slovakia 1>NUL Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -63 at uk.me.parabola.imgfmt.app.srt.Sort$SrtCollator$PositionIterator.next(Sort.java:468) at uk.me.parabola.imgfmt.app.srt.Sort$SrtCollator.compareOneStrength(Sort.java:396) at uk.me.parabola.imgfmt.app.srt.Sort$SrtCollator.compare(Sort.java:363) at uk.me.parabola.imgfmt.app.mdr.PrefixIndex.createFromList(PrefixIndex.java:73) at uk.me.parabola.imgfmt.app.mdr.PrefixIndex.createFromList(PrefixIndex.java:99) at uk.me.parabola.imgfmt.app.mdr.Mdr17.addPois(Mdr17.java:100) at uk.me.parabola.imgfmt.app.mdr.MDRFile.writeSections(MDRFile.java:301) at uk.me.parabola.imgfmt.app.mdr.MDRFile.write(MDRFile.java:258) at uk.me.parabola.mkgmap.combiners.MdrBuilder.onFinish(MdrBuilder.java:365) at uk.me.parabola.mkgmap.main.Main.endOptions(Main.java:440) at uk.me.parabola.mkgmap.CommandArgsReader.readArgs(CommandArgsReader.java:126) at uk.me.parabola.mkgmap.main.Main.main(Main.java:114)
