Follow-up Comment #17, bug #60357 (project octave):

Attached is a one-line patch that at least means qz returns 3 eigenvalues. 
The patch is


          //tmp.resize (cnt);  // Trim vector to number of return values


Octave was trimming down the eigenvalue matrix which was originally created to
size 3x1 to the number of eigenvalues returned from LAPACK.  Since the third
eigenvalue can take any value, why not make it 0?  That's what this patch
effectively does since the matrix is effectively created with all 0 values to
begin with.
