[Octave-bug-tracker] [bug #58617] cell2struct silently truncates char matrices

[Rik]

Follow-up Comment #2, bug #58617 (project octave):

Taking a look at the code in ov-struct.cc for cell2struct I see


  if (! (args(1).iscellstr () || args(1).is_char_matrix ()))
    error ("cell2struct: FIELDS must be a cell array of strings or a character
matrix");

  int dim = 0;

  if (nargin == 3)
    {
      if (! args(2).is_real_scalar ())
        error ("cell2struct: DIM must be a real scalar");

      dim = args(2).int_value () - 1;
    }

  if (dim < 0)
    error ("cell2struct: DIM must be a valid dimension");

  const Cell vals = args(0).cell_value ();
  const Array<std::string> fields = args(1).cellstr_value ();

  octave_idx_type ext = (vals.ndims () > dim ? vals.dims ()(dim) : 1);

  if (ext != fields.numel ())
    error ("cell2struct: number of FIELDS does not match dimension");


So, the problem is a little deeper.  Have to look at cellstr_value() and see
how it operates.
