#108 Data backup does not work on i386 and creates always a 50 byte file

[Markus Koschany]

Osmo's backup feature works as intended on amd64/x86_64 systems but it does not work on i386 and probably other 32bit architectures.

How to reproduce:

1. Compile Osmo for i386 or use the official Debian package (version 0.2.12 and 0.2.14 are affected)
2. Start Osmo and create a random calendar entry. Save everything.
3. Use the backup feature. Osmo creates a backup file which size is always 50 byte.
4. Try to restore the backup. All data is gone.

I can rule out that it has something to do with custom build flags. I have built Osmo without any hardening flags on i386 but the backup feature is still broken.

This is Debian bug: https://bugs.debian.org/813414

Hi Markus,

Thank you for reporting the issue.

It seems there is a problem with libarchive and the way it handles file sizes on i386.
I applied a temporary workaround to Osmo. The version in trunk handles backups on i386 correctly.

Thanks again for the heads-up!
