xfsp_repair segfault (3.1.4 & 3.1.6)

[nanashi]

Hi,

I have a corrupted RAID5 xfs filesystem from an intel SS-4000 NAS storage.
I'm using slackware-current with 2.6.39.3-smp kernel (32bit & 64bit)
When i try xfs_repair I get

xfs_repair: dir2.c:2133: process_dir2: Assertion `(ino
!=mp->m_sb.sb_rootino && ino != *parent) || (ino ==
mp->m_sb.sb_rootino && (ino == *parent || need_root_dotdot == 1))'

I try both x86 and x86_64, I build 3.1.4 and 3.1.6 with DEBUG=-DNDEBUG 
and both continue but gave me a segfault

[23978.718305] xfs_repair[25800]: segfault at 7fffa1d81ff0 ip 
00007f15c1852049 sp 00007fffa257f048 error 6 in 
libc-2.13.so[7f15c1715000+19b000]

I try xfs_metadump and I get segfault too.

The partition is 2.2TB and I don't have enough space to dd it to an image.

I attach the xfs_repair output before the segfault.

any help is appreciated.
