[mkgmap-dev] Crash "Illegal Capacity" when converting map

Mon Dec 19 18:05:06 GMT 2016

Yes, sorry for the europe-latest thing, but I have a crop polygon that 
includes many countries and sadly I could not narrow it down.
I wondered if resolution and max nodes does not contradict a bit, thanks 
for letting me know it really does

Will use a lower resolution
