[GRASS-dev] Re: [GRASS GIS] #402: v.in.ogr buffer overflow

[Jachym Cepicky]

 (Hi,

(http://trac.osgeo.org/grass/ticket/402 returns 500 Internal Server
Error, so I'm replying via mailing list)

same problem here:

Ubuntu 8.10:

ii  gdal-bin                                  1.5.2-4.1~intrepid
ii  libgdal1-1.5.0                            1.5.2-4.1~intrepid
ii  libgdal1-1.5.0-grass                      1.5.2-1
ii  libgdal1-dev                              1.5.2-4.1~intrepid

applyes for GRASS 6.3 (les-ejk ubuntu package) and 6.4 (fresh source
compilation)

the problem seems to be in ubuntu gdal package
