在 Ubuntu 上运行 extundelete 时出现分段错误 - 该怎么办？

Question

我有一个分区原始映像，我试图在其上运行extundelete以从ext4文件系统中取消删除某些文件。不幸的是 extundelete 退出时出现了一个段错误。

有什么我可以做的吗？

root@ubuntu-VirtualBox:~# extundelete --restore-all mmcblk0p7.raw 
WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates 
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible.  You should unmount the
file system and check it with fsck before using extundelete.
Would you like to continue? (y/n)

dmesg 只给出：

事实证明 ubuntu 构建存在一些问题。从源代码构建有助于：

apt-get remove extundelete
apt-get install build-essentials e2fslibs-dev
tar -xjf extundelete-VERSION.tar.bz2
cd extundelete
./configure
make
src/extundelete --restore-all image.raw
