David> Both: it needs to be fixed, but it's (mostly) benign since the only

David> I was hoping someone who knows and could test the MCA code better

David> Tony, below is a patch that fixes the unwind info enough that the
David> warning/error goes away.  The unwind-info may not be 100% correct

David> that.
