	Hi!  I recently installed g++-1.34.2 and libg++-1.34.0 on our
Sun3 OS 4.0.1 machine.  The following program could be compiled but
when executed, it produced the out of memory error.  It looks like
there's a bug in new or delete function.
This program is a kind of stupid but easy to explain the problem.

=========================================================================
#include <stream.h>
#include <math.h>
#include <ACG.h>
#include <Uniform.h>
#include "floatAVec.h"

main()
{
  floatAVec array(100);
  floatAVec window(100);
  floatAVec res;
  ACG gen;
  Uniform r(0.0,1.0,&gen);

  for (int i = 0; i < 100; i++)
    {
      array[i] = r();
      window[i] = cos(PI*(i-50)/100);
    }  

  for (i = 0; i < 1000000; i++)
    res = product(array, window);

  exit(0);
}

$ newtest
default_new_handler: out of memory... aaaiiiiiieeeeeeeeeeeeee!


This kind of memory allocation problem is critical for the people who are
doing numerical computation!
