cout with manipulator "fixed" gives MemReadError

Hi everybody,

today I spent more than 1h to find this bug in my program. The problem is the following:

If I declare an array of doubles, do not initialize the array and then use cout with the manipulator "fixed" I get a segmentation fault.

If I initialize the array before using cout with "fixed" everything works fine. Why does an uninitialized array causes this error?

Here is my code:

Code:

---

using namespace std;
#include <iostream>
#include <conio.h>

int main (void)
{
  double array[20];
 
  for(int i=0; i<20; i++)
    cout << array[i] << "\n"; 
 
  for(int i=0; i<20; i++)
    cout << fixed << array[i] << "\n"; 
 
  return 0;
}

---

Thanks for your help!

greetings, nitron
