** Description changed: Binary package hint: tar I have a backup script which is doing incremental backups on NFS share. I am using an -g (--listed-incremental) option for that purpose. If the snapshot file does not exists (which means tar is doing full backups) everything works flawlessly. The problem occur whenever incremental backup has to be taken. Tar crashes immediately with Segmentation Fault error. I have tried to isolate NFS issues and copied the snapshot file to local storage and instructed tar to put the archive to local drive as - well. The result was exactly the same. When i tried with copying just - small amount of data problem did not occur. I have recently migrated - from Gentoo where tar worked perfectly with this setup. + well. The result was exactly the same. The problem occurs whenever the + root directory "/" is included in the backup. + + TEST CASE: + $ tar cpf /tmp/test.tar -g /tmp/snap / --exclude="*" + $ tar cpf /tmp/test.tar -g /tmp/snap / --exclude="*" + Segmentation fault + + After applying the fix in the linked branch, tar no longer segfaults. The patch is taken from this upstream commit: + http://git.savannah.gnu.org/cgit/tar.git/commit/?id=e21d54e8cd3d8026ad56f90cc6bde831106c2cb9 + + The bug is a regression introduced in Maverick.
