Hello all I am trying to build an unicode map of Israel or Greece but they always fail with java.lang.AssertionError as soon as I add --index to command line. I have tried both my own style and default one. Only if I use an small osm file as input it succeeds. The simplest command line that throws the error is: java -Xmx3G -ea -jar mkgmap_trunk.jar --bounds=bounds.zip --route --unicode --family-name="Test" --family-id=190 --product-id=1 --description="Test" --series-name="Test" --overview-mapname=55190000 --mapname=55190000 --index --style=default --remove-ovm-work-files=true 51178007.o5m Time started: Tue Sep 22 10:37:47 CEST 2020 Number of MapFailedExceptions: 0 Exception in thread "main" java.lang.AssertionError: 914 at uk.me.parabola.imgfmt.app.FileBackedImgFileWriter.put1u(FileBackedImgFileWriter.java:166) at uk.me.parabola.imgfmt.app.mdr.Mdr8.writeSectData(Mdr8.java:45) at uk.me.parabola.imgfmt.app.mdr.MDRFile.writeSection(MDRFile.java:421) at uk.me.parabola.imgfmt.app.mdr.MDRFile.writeSections(MDRFile.java:373) at uk.me.parabola.imgfmt.app.mdr.MDRFile.write(MDRFile.java:269) at uk.me.parabola.mkgmap.combiners.MdrBuilder.onFinish(MdrBuilder.java:334) at uk.me.parabola.mkgmap.main.Main.endOptions(Main.java:675) at uk.me.parabola.mkgmap.CommandArgsReader.readArgs(CommandArgsReader.java:125) at uk.me.parabola.mkgmap.main.Main.mainStart(Main.java:144) at uk.me.parabola.mkgmap.main.Main.main(Main.java:115) Test files can be found are 51178007.o5m <https://alternativaslibres.org/tmp/51178007.o5m> and jerusalem.o5m <https://alternativaslibres.org/tmp/jerusalem.o5m>
