I would have been surprised if that was it, but worth checking (thanks).
So, it looks like something is stomping on the libc malloc data structures
causing libc to segfault.  Possibly a use-after-free, or freeing unalloc'd
memory, I would guess.  Could you try linking with Electric Fence and then
running that on the binary?  You can set the environment variable MALLOCLIB
to /usr/lib/libefence.a, then do "make distclean && make" in xfsdump - you
should still see a segv, but hopefully at the point of failure now, not at
some point afterward.

Also, could you tar+gz up the contents of your /var/lib/xfsdump directory
and send that to me please?

thanks.
