Follow-up Comment #5:

The result given with arpack-3.6.1 (original submission) is correct (you can
try to increase opts.maxit and compare). If you look at the changes between
3.5.0 and 3.6.1 https://github.com/opencollab/arpack-ng/blob/master/CHANGES
you see just one change to the algorithm (btw, by me) which could be
responsible of a faster convergence od arpack. Dimitri confirmed the original
result on a different platform, so I think we should change the test in order
to reflect this improvement in arpack. What happens if you decrease opts.maxit
to 4 or even smaller numbers?
