Admittedly this is a rather crytic message but it means that the
algorithm in dgesdd for determining the singular values did not
converge. From the Lapack documentation for dgesdd
INFO (output) INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.
> 0: DBDSDC did not converge, updating process failed.
