Details:

 Hello,

I encounter memory access problems with Matrix in oct files with octave
versions > 3.4.3.

For example, the following code works with octave 3.4.3, but fails with octave
3.6.2.
[built with 'CXXFLAGS=-O2 mkoctfile inspect.cc' on MacOS 10.6.8]

Is this a bug or am I wrong (I have read the docs, the forums, and this code
is quite simple...)?

Thanks in advance.

 Best regards,

Sylvain.

using namespace std;

DEFUN_DLD (inspect, args, , "inspect")
{
  Matrix signal = Matrix (1,2);

  signal(0) = 123.456;

  cout << "Will be displayed..." << endl;

  cout << signal(0) << endl;

  cout << "Will NOT be displayed on recent Octave versions..." << endl;

  return octave_value(0);
}

// End Of File
