[mkgmap-dev] patch for crash in MapSource

Thu Feb 8 21:04:19 GMT 2018

Hi Gerd

I can see that , but again no probs here when I used your map

For my final trial i used some pbf files of the UK which were split last 
year without the align for dem option

This still worked !, ie no crashes ;

good point - have to check if the dem poly includes empty hgt files.

Will do some more checking tomorrow.

Again, congratulations on a major achievement!
