             I'd like to see if other Mac users experience the same
        issue.  We could
             increase the tolerance if it consistently fails by the same
        amount on
             multiple different Mac systems.

        On my Fedora 19 (x86_64) it passes with reference BLAS  but
        fails with ATLAS
        and OpenBLAS.


    Could you please print out and post the actual error text?  Thanks.

Thanks. That's a strange one. As with the error Carlo is seeing, I hope David can investigate this one as well.
