[mkgmap-dev] patch for crash in MapSource

Fri Feb 9 08:38:52 GMT 2018

Hi Gerd

I'm getting the same issues when I split Devon with max nodes 10 000

in fact anything below 40 000 causes a crash

The tests I made yesterday  was with max nodes 80 000, so perhaps 
somehow its linked to the maxnodes?
