Go4Expert - A weird segmentation fault error

Hi there,

There is a weird segmentation fault error. The following code runs fine

Code:

#include <stdlib.h>

#include <stdio.h>



main()

{

    int matrixSize = 1000;

    int i,j;

    

    double a[matrixSize][matrixSize];

    for (i = 0; i < matrixSize; i++)

        for (j = 0; j < matrixSize; j++)

            a[i][j] = rand() % 10;

            

    double b[matrixSize][matrixSize];

    for (i = 0; i < matrixSize; i++)

        for (j = 0; j < matrixSize; j++)

            b[i][j] = rand() % 10;



    return 0;

}

But when I try to initialize one more 2D array, I get "segmentation fault" exception:

Code:

#include <stdlib.h>

#include <stdio.h>



main()

{

    int matrixSize = 1000;

    int i,j;

    

    double a[matrixSize][matrixSize];

    for (i = 0; i < matrixSize; i++)

        for (j = 0; j < matrixSize; j++)

            a[i][j] = rand() % 10;

            

    double b[matrixSize][matrixSize];

    for (i = 0; i < matrixSize; i++)

        for (j = 0; j < matrixSize; j++)

            b[i][j] = rand() % 10;



    return 0;

}

Any advice on what can be a potential cause would be greatly appreciated..

Thank you in advance.
