                 Summary: C++ function crashes 64 bit Octave, but not 32 bit.
                 Project: GNU Octave

    _______________________________________________________

Details:

The following code is a stripped down example "test64.cc":

#include <octave/oct.h>

DEFUN_DLD (test64, args, ,
  "\n")
{

  const int    L      = args(0).int_value();

  Matrix g(L,1);

  return octave_value (g);
}

I compile using "mkoctfile test64.cc"

On 32 bit Linux (Ubuntu with Octave 3.2.3) this works perfectly fine,
"test64(20)" return a vector of random garbage, and up until know this code
has always worked.

It also workd on Octave 3.2.4 on WinXP.

On 64 bit Fedora, Octave 3.2.4 I get an immidiate crash:
