Details:

In testing Octave built for i686, I am seeing 2 test failures in eigs.m.

Octave is built against OpenBLAS in this configuration.


 A = 1i * magic (100);
 opts.v0 = (1:100)';
 opts.maxit = 1;
 warning ("off", "Octave:eigs:UnconvergedEigenvalues", "local");
 d = eigs (A, 4, "lm", opts);
 assert (d(4), NaN+1i*NaN);
!!!!! test failed
ASSERT errors for:  assert (d (4),NaN + 1i * NaN)

  Location  |  Observed  |  Expected  |  Reason
     ()      6.662e-15+5.0765e-12i   NaN+NaNi     'NaN' mismatch


 A = 1i * magic (100);
 Afun = @(x) A * x;
 opts.v0 = (1:100)';
 opts.maxit = 1;
 opts.isreal = false;
 warning ("off", "Octave:eigs:UnconvergedEigenvalues", "local");
 d = eigs (Afun, 100, 4, "lm", opts);
 assert (d(4), NaN+1i*NaN);
!!!!! test failed
ASSERT errors for:  assert (d (4),NaN + 1i * NaN)

  Location  |  Observed  |  Expected  |  Reason
     ()      -6.8217e-22+9.1207e-12i   NaN+NaNi     'NaN' mismatch
