Nope.

Another thing that just occurred to me - what compiler are you using? We had a report last week on #xfs that xfsdump was failing with bad checksums because of link time optimisation (LTO) in gcc-4.8.0. When they turned that off, everything worked fine. So if you are using 4.8.0, perhaps trying a different compiler might be a good idea, too.
