Hi,
I need to look into this more obviously and try other dumps etc, but I
even tried extracting a single (smaller) directory and it also segfaulted,
has dump been tested properly with ext4?
# restore -f ../p34-root-2010-03-02.ext4dump -r .
Segmentation fault (core dumped)

And from another day:
p34:/x2/bup/p34/2010-03-01/d# restore -f ../p34-root-2010-03-01.ext4dump
-r .
Segmentation fault (core dumped)

Does anyone use dump/restore with ext4?

Was dump/restore statically or dynamically linked? And with which
version of libext2fs from e2fsprogs?

Hi,
I tried restoring from two different datasets on one machine <10GB and another
one ~30GB, all files are corrupted, other users report the same problem:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=511651
https://lists.ubuntu.com/archives/universe-bugs/2009-June/098729.html
Per your requests:
They are dynamically linked.
This is standard Debian Testing x86_64, nothing custom (in the
distribution).
