Re: [mapserver-users] MapServer 5.4.0 Buffer Overflow Error
Thx Umberto, I'll try to reinstall GDAL then, thx :). On Wed, May 20, 2009 at 12:39 AM, Umberto Nicoletti umberto.nicole...@gmail.com wrote: This is a known issue with recent Ubuntu systems which is caused by a special compiler feature (called fortify) which enables a protection system against the most common memory management errors. Unfortunately as a result of this GDAL will break and dependent sw become unusable (mapserver, grass, qgis, etc). Luckily there is a workaround: remove the gdal installed by canonical and install the packages from ubuntu gis project instead: https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable You may have to recompile mapserver after this.
