[Dmitri A. Sergatskov]

Follow-up Comment #7, bug#40357 (group octave):

And on Raspberry Pi 4 (8G mem + 16G swap) / Fedora 39:

octave:1> __octave_config_info__.ENABLE_64
ans = 1
octave:2> x = logical(sparse(100000,100000));
octave:3> y = sparse(100000,100000);
octave:4> ii = full(logical(sprand(100000,1,0.3)));
octave:5> x(ii,:) = y(ii,:);
Killed

>From system log:
