Follow-up Comment #163, bug #57591 (project octave):
The Windows 32bit runners on GitHub are failing this test with the following
error:
>>>>> processing C:\msys64\mingw32\share\octave\7.0.0\m\sparse\gmres.m
***** test
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, resvec] = gmres (@(x) A*x, b, dim, 1e-10, dim,...
@(x) x./diag (A), [], []);
assert (x, A\b, 1e-9*norm (x, Inf));
[x, flag] = gmres (@(x) A*x, b, dim, 1e-10, 1e6,...
@(x) diag (diag (A)) \ x, [], []);
assert (x, A\b, 1e-9*norm (x, Inf));
[x, flag] = gmres (@(x) A*x, b, dim, 1e-10, 1e6,...
@(x) x ./ diag (A), [], []);
assert (x, A\b, 1e-7*norm (x, Inf));
!!!!! test failed
out of memory or dimension too large for Octave's index type
So, it could be the Linux OOM killer at work here.
