frozen_at_z_len problems

[Ben Sapp]

I am writing a file in c++ to be dynamically linked with Octave.  When
ever I run it there is a core dump and I can not figure out what it does
not like.  Before it core dumps I always see a warning like this:

idx-vector.cc:589: failed assertion `frozen_at_z_len == z_len'

I have looked at idx-vector.cc and I still am not any closer to
understanding.  

Here is the code, it always crashes on the second to last line.  
---------------------------------------------------------------
    octave_stdout << "whichBound =\n" << whichBound << "\n";
    tmp_rows = idx_vector(Range(1.0,1.0));
    octave_stdout << "tmp_rows =\n " << tmp_rows << "\n";
    octave_stdout << "tmp_cols =\n" << tmp_cols << "\n";
    Matrix temp = Matrix(whichBound);
    octave_stdout << "temp =\n" << temp << "\n";
    temp = Matrix(temp.index(tmp_rows,tmp_cols));
    octave_stdout << "temp =\n" << temp << "\n";
---------------------------------------------------------------

The variables are declared like this:
---------------------------------------------------------------
RowVector whichBound
idx_vector tmp_rows;
idx_vector tmp_cols;
---------------------------------------------------------------

The output looks like so:
---------------------------------------------------------------
whichBound =
 -0 -0 -0 0 0 0 1 1 1
tmp_rows =
 0

tmp_cols =
0
1
2
3
4
5

temp =
 -0 -0 -0 0 0 0 1 1 1

idx-vector.cc:589: failed assertion `frozen_at_z_len == z_len'
error: Abort -- stopping myself...
Abort (core dumped)
---------------------------------------------------------------

Any hints as to what the problem is would be greatly appreciated. 

Thanks.
