Subject: xfsprogs: xfs_check SEGV
Date: Thu, 14 Feb 2008 22:42:28 +1100

Package: xfsprogs
Version: 2.8.11-1
Severity: critical
Justification: breaks the whole system

I have a filesystem which causes a SEGV when I try to check it.

The problem started when I unexpectedly powered the machine down causing some
data loss.  When I booted it up again the kernel gave errors about corrupted
data structures (which I unfortunately didn't make a note of).  Now when I
try to check it (on another machine) it gives the following.

NB The filesystem has no secret data, I would be happy to give you a copy, I
could put it on a machine on the net that you can access or give you an IDE
disk with a copy if you are in Melbourne.

xfs_check was replaced by xfs_repair long ago.
