ozf2 2GB bug

[Wolfgang16]

Hello,



I tried some ozf2 maps > 2 GB with oruxmaps. This always results in an error "offset < 0: -123456789"

where the number is almost exactly equal to filesize - 2^32. This looks like a wrap around with a signed integer.

Hello!



the ozf2 format version that I know stores the pointers to the zoom levels in 4 bytes. So, it doesn't allow > 2gb files.



If you can share one of your maps with me, I can check it.

I can give you a download link, but since the map might be copyright protected I wouldn't like to publish it here. Can I send it via email or any other option?

Yes, there is a bug with maps larger than 2gb.



I found that the limit is 4gb. The offset are stored in unsigned integers.

it works with version 7.2.0

I have tested ozf2 files up to 3.86GiB

Thanks
