[mkgmap-dev] Tile with very few nodes fail to compile

Sat Nov 7 14:25:56 GMT 2009

Hi List!

Since yesterday a tile of europe fails to compile and mkgmap crashes
with an exception. I would have to reduce max-nodes to 32000 to get this
area compiled. Problem is that I do not want to compile complete europe
with that low value of max-nodes. Here is the areas.list file which
contains this tile already reduced to a size where it nearly crashes:

And mkgmap crashes with the following exception:

Number of nodes in the created tile is 50935.

mkgmap version is 1355.

Why are so small tiles crashing?
