The memset in cb_add_inogrp will segfault when the index oldsize

A second bug also occurs because we already compensate for the
length of each item in oldsize so are 32bit wrap becomes a 40bit
wrap.
Hi -
Are there any testcases for these? xfsdump is alien code, I swear;
I'm not quite sure offhand how to tickle any of these bugs.
Thanks,

No I thought simple examination shows the bug.
It was a customer bug.
The number of inodes that we needed before wrapping was a couple hundred
inodes.
