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

Mon Dec 19 17:43:24 GMT 2016

Hi Gerd,

you can find the workfolder and script here:

https://www.jmuehldorfer.de/owncloud/index.php/s/yAKF6E47Y9pyxAd

Sorry for the chaos in the options, the script was created piece by 
piece, they are not in logical order

You also need to add a copy of bounds.zip and sea.zip into the preload 
folder, I did not include that because you likely already have them on 
your machine

And you might need to adjust java ram settings in the script

Hope you can trigger the bug, thanks for looking into this!
Luckily one recent map converted just fine, and I don't need mkgmap 
again until end of January
