oss.sgi.com infrastructure is not well maintained, I'm sorry about that,
but it's up to SGI to fix anything that needs fixing, I'm afraid.

Which is a pity, because a well-maintained bug tracker would be pretty
useful.

That said, reporting to the list is also probably a good idea.

You didn't say what version of xfsprogs you tested, but there have
been a few independent fuzz-related fixes recently; you might just retest
against what's currently in the git tree, and see if we got lucky.  ;)
