Follow-up Comment #2, bug #53912 (project octave):

The problematic test is:



dim = 100;
A = spdiags ([[1./(2:2:2*(dim-1)) 0]; 1./(1:2:2*dim-1);[0
1./(2:2:2*(dim-1))]]', -1:1, dim, dim);
A = A'*A;
b = rand (dim, 1);
[x, flag] = gmres (@(x) A*x, b, dim, 1e-10, 1e6,@(x) x ./ diag (A), [], []);



Dmitri.
