[Octave-bug-tracker] [bug #32683] incorrect ndarray concatenation

[Rik]

Update of bug #32683 (project octave):

                Severity:              3 - Normal => 4 - Important          
                  Status:                    None => Confirmed              
                 Summary: icompatible behaviour of ndarray concatenation =>
incorrect ndarray concatenation

Follow-up Comment #2:

There is clearly something deeply wrong here.  Reversing the order of the
concatenation of the zeros() and ones () produces strange sequences of the
coefs matrix.  It appears that Octave is sampling uninitialized memory.

For example,


coefs = [ ones(1,2,2) ; zeros(3,2,2) ]
coefs =

ans(:,:,1) =

    0.0000e+00    0.0000e+00
    0.0000e+00    0.0000e+00
    0.0000e+00    0.0000e+00
   2.1031e-316   1.9281e-316

ans(:,:,2) =

    0.0000e+00    0.0000e+00
    0.0000e+00    0.0000e+00
    0.0000e+00    0.0000e+00
   1.8978e-316   2.0065e-316


But the result varies and sometimes I get all zeros.
