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

Mon Dec 19 05:41:26 GMT 2016

Hi Jakob,

this seems to be a special case in the (OSM) data. I can probably add a check to avoid the crash

but I'd like to know what happens and I was not yet able to reproduce it.

I assume it happens only for one input file?

Please post a link to that file and maybe your style and options if needed.

Gerd

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

Hi,

currently I am getting a ton of crashes like this:

Any idea what might be wrong?

It happened in 3706 to 3730
Sometimes the exact same conversion process (splitting+mkgmap) on the
exact same OSM file works, but that is rarely the case
If you need any more information, or an upload of the style and split
tiles that cause the crash, let me know.

Hope you can help
Jakob
