Follow-up Comment #2, bug #59486 (project octave):

The buildbots seem to struggle with the newly added test.
E.g.:

>>>>> processing
/scratch/buildbot/workers/jwe-debian-x86_64-0/stable-clang-debian-save/src/scripts/sparse/eigs.m
***** testif HAVE_ARPACK <*59486>
 A = magic (5);
 d = eigs (A, [], 1);
 assert (d, 65, 150*eps);
!!!!! regression: https://octave.org/testfailure/?59486
ASSERT errors for:  assert (d,65,150 * eps)
  Location  |  Observed  |  Expected  |  Reason
     ()           65           65        Abs err 5.6843e-14 exceeds tol
3.3307e-14 by 2e-14


Should the tolerance for this test just be relaxed? Or is there something more
to it?
