Hi Gerd,
Interesting to hear because on Sicily there are hardly any cycle routes, if
any, on OSM, so it could be also associated with something else.
Can you give just the location of that particular roundabout on the osm.org map
so I can see if there are similarities with other roundabouts?
I think about too many OSM nodes, the roundabouts on the mkgmap maps are
sometimes distorted if drawn with a lot of nodes. Maybe this could cause
crashing of the device?
Another more likely cause could be that I use an invisible line type for 0x0c:
junction=roundabout [0x0c road_class=1 road_speed=1 resolution 24 continue
with_actions]
junction=roundabout {set access=no}
The line that is rendered on my map is not accessible, for instance an
unclassified 'white' road with 0x06 is drawn on top of this invisible 0x0c.
Possible problem is that it still has routable parameters (road_class and
road_speed), maybe this causes the crashes? A solution would be to replace all
highway=* & junction=roundabout with a non routable line type on top of this
0x0c for rendering the correct line type. In the default mkgmap style this
problem does not occur because all roundabouts are rendered with the same style
and just one line (0x0c).
