Hi Gerd I've been tearing my hair out over this one. With the test data supplied, the SubDivision structure in the main output .img file is incorrect. Just changing how areas are split (ie relaxing the constraint that bounds are exactly representable at the zoom/shift level) stops the crash, so this is what I've done in the attached patch. Sometime soon I'll try and work out when/where it goes wrong but I've been looking in so many places, thinking I'd tracked down the problem, only to find no difference, that I want to give up for a while.

I'll have a look. I didn't intentionally change extended type behaviour, but shapes will end up in different subdivisions with the option applied

The problem seems to be caused by the new --order-by-decreasing-area option, if I remove that from the options file the problem is gone.
@Ticker: Do you have time to analyse it? I assume the problem is that we set a flag like "extended type points exist" and later remove the corresponding data. Does that ring a bell?

Hello everybody, i use mkgmap r3706. It run 2 times. The first one makes the img-files. The second one makes the mdr/mdrx files. The first step works fine, without error-messages, but the second step produces an error message and crashes: "Exception in thread "main" java.lang.AssertionError: Invalid label offset found 1315595 at uk.me.parabola.imgfmt.app.lbl.LBLFileReader.fetchLabel(LBLFileReade r. java:87) at uk.me.parabola.imgfmt.app.trergn.RGNFileReader.fetchPointsCommon(RG NF ileReader.java:123) at uk.me.parabola.imgfmt.app.trergn.RGNFileReader.pointsForSubdiv(RGNF il eReader.java:84) at uk.me.parabola.imgfmt.app.map.MapReader.pointsForLevel(MapReader.ja va :119) at uk.me.parabola.mkgmap.combiners.MdrBuilder.addPoints(MdrBuilder.jav a: 273) at uk.me.parabola.mkgmap.combiners.MdrBuilder.onMapEnd(MdrBuilder.java :1 78) at uk.me.parabola.mkgmap.main.Main.endOptions(Main.java:600) at uk.me.parabola.mkgmap.CommandArgsReader.readArgs(CommandArgsReader. ja va:128) at uk.me.parabola.mkgmap.main.Main.mainStart(Main.java:135) at uk.me.parabola.mkgmap.main.Main.main(Main.java:106)" When i use mkgmap 3702 an error message at the first step appears, the second step works fine: "SCHWERWIEGEND (ShapeMergeFilter): ..\Splitter\88000004.osm.pbf: ignoring shape w ith id 364926659 and type 0x13 at resolution 24, it has 4 points and has an empt y area" The OSM-Data is "nordrhein-westfalen.osm.pbf". An other map "Kanaran" works fine, without error. Whats the reason for this and what can i do? Best regards Arndt
