OK, I tried to narrow this down.

It looks a bit weird though. The problem doesn't seem to be connected to
one feature, tag or element. It looks like it's a sort of overflow, like
some maximum number has been exceeded.

My minimum config to recreate the problem:

The command line:
/usr/java/jre1.6.0_16/bin/java -jar mkgmap-r1455/mkgmap.jar --latin1
--family-id=1331 --product-id=1 --style-file=mkgmap-style-topotest/
--tdbfile=yes --remove-short-arcs 10000040.osm.gz

The style consist of:
 - no relations file
 - no polygons file

The options file is:
levels = 0:24,1:23,2:22,3:21,4:20,5:18,6:16,7:14

The points file has just one line:
place=hamlet [0x1100 level 4]

The lines file looks like this:
highway=unclassified   [0x06 road_class=1 road_speed=2 level 3]
highway=tertiary       [0x05 road_class=1 road_speed=3 level 3]
highway=secondary      [0x04 road_class=2 road_speed=3 level 4]
highway=primary        [0x03 road_class=3 road_speed=4 level 5]
highway=cycleway       [0x16 road_class=0 road_speed=1 level 2]
highway=pedestrian     [0x06 road_class=1 road_speed=2 level 3]
highway=residential    [0x06 road_class=0 road_speed=2 level 3]
highway=footway        [0x16 road_class=0 road_speed=0 level 3]
highway=service        [0x07 road_class=0 road_speed=2 level 3]
highway=track          [0x0a road_class=0 road_speed=1 level 3]
highway=path           [0x16 road_class=0 road_speed=1 level 3]
highway=living_street  [0x06 road_class=0 road_speed=1 level 3]

If I remove any one of these lines from the points or lines file the
problem disappears.

If I remove the road_class and road_speed definitions from e.g.
unclassified the problem disappears.

If I move e.g. the pedestrians into level 4 or 7 the problem persists.

The OSM file is one tile made with the mkgmap splitter from the
Geofabrik Europe file, it can be found here:

Any ideas? Something more I can test?
