Hi Radim,

I made this change and with qint64 (typedef qint64 grass_off_t;) QGIS does
not crash, but the geometry just disappears after editing. Please see here:


The same is happening with GRASS6.

With typedef qint32 grass_off_t it still crashes.

I'm using GRASS 7.0.1-2~ubuntu14.04.1 from
and GRASS 6.4.3-3 from http://packages.ubuntu.com/trusty/grass
on Xubuntu 14.04 LTS.
