Follow-up Comment #3, bug #32683 (project octave):
The attached patch includes a test for this confirmed bug.
I suggest to include this into the repository.
BTW: I noticed that each input array is written at the beginning of the output
array. It seems that the offset for writing the 2nd and following arrays is
incorrectly reset to 0 or not correctly updated,
[ zeros(4,2,2);
ones(3,2,2) ;
2*ones(2,2,2) ;
3*ones(1,2,2) ;
]
ans(:,:,1) =
3.0000e+00 3.0000e+00
2.0000e+00 2.0000e+00
1.0000e+00 1.0000e+00
0.0000e+00 0.0000e+00
2.3715e-322 0.0000e+00
2.3715e-322 0.0000e+00

2.1220e-314 1.8854e-316
1.7468e+243 4.7924e-322
ans(:,:,2) =
3.0000e+00 3.0000e+00
2.0000e+00 2.0000e+00
1.0000e+00 1.0000e+00
0.0000e+00 0.0000e+00
2.3715e-322 0.0000e+00

2.1220e-314 1.8854e-316
8.3834e+242 4.7924e-322
P.S,; This bug occurs not only on MacOS and dev-version but also in Octave
3.4.0., 3.4.1 and 3.4.2 on Linux.
