Update of bug #55132 (project octave):
Status: None => Need Info

Follow-up Comment #2:
It's weird, however, that it is failing. The third output of bicg is supposed
to be
RELRES is the ratio of the final residual to its initial
value, measured in the Euclidean norm.
which in this case should be exactly
norm (b - A * x) / norm (b)
Could the original reporter edit the file bicg.m and change the test to
assert (norm (A*x - b) / norm (b), 0, relres);
and retest?
If that doesn't work then try this
assert (norm (b - A * x) / norm (b), 0, relres + eps);
