this is unfortunately one of the worst cases to fix: an error inside
a lapack routine, with no obvious reason (I assume that your system
is ok: otherwise some error would have shown up much earlier). Are
you running in parallel or serially? and what libraries are you using?
sometimes machine-optimized libraries are very fast but not so reliable.
