[mkgmap-dev] Splitter: Assertion on very large node id

Tue Mar 1 13:25:30 GMT 2016

Hi Lambertus,
the code in line 260:
		assert flon >= -180.0 && flon <= 180.0;  
So it is not related to ids.  

Gerd

Betreff: [mkgmap-dev] Splitter: Assertion on very large node id

Using an o5m file with a huge node-id seems to break splitter-r427:

[..]
3,200,000,000 nodes processed... id=3982721872
3,210,000,000 nodes processed... id=200000782524
Exception in thread "main" java.lang.AssertionError

The o5m file is a combination of a recent planet dump and an address
file for France, from here (banco-france-o5m.zip):

It looks like a signed 32 bit integer problem? Splitter is running on
Linux x86_64, Java OpenJDK 1.7.0_95 64-bit (mixed mode).
