Update of bug #46683 (project octave):

                Category:         Octave Function => Libraries              
                  Status:                    None => Confirmed              
                 Release:               4.0.1-rc1 => dev                    
        Operating System:       Microsoft Windows => Any

Follow-up Comment #1:

This test fails also with Debian with the current version of OpenBLAS, but
does not require loading Java to trigger the test failure. Maybe more than one
interaction leading to this happening?


$ LD_LIBRARY_PATH=/usr/lib/libblas:/usr/lib/lapack octave-cli --eval "test
svds"
PASSES 6 out of 6 tests


$ octave-cli --eval "test svds"
warning: svds: returning fewer singular values than requested
warning: svds: try increasing the value of sigma
***** testif HAVE_ARPACK, HAVE_UMFPACK
 [u2,s2,v2,flag] = svds (A,k,0,opts);
 s2 = diag (s2);
 assert (flag, !1);
 tol = 10 * eps() * norm(s2, 1);
 assert (s2, s(k:-1:1), tol);

!!!!! test failed
ASSERT errors for:  assert (s2,s (k:-1:1),tol)
