Hi !
I've writen the following program :


#include <stdio.h>

int main ()
{
        int p[4];
        p[0]=1;
        p[1]=2;
        p[2]=3;
        p[3]=4;
        p[4]=5;

        printf ("%i, %i, %i, %i, %i\n", p[0], p[1], p[2], p[3],
p[4]);
        return 0;
}

I compile it with :

 gcc -o test test.c -Wall

and when i launch it, the output is :

 julien:$> ./test
1, 2, 3, 4, 5

Should I not get a SIGSEV from the system ? Isn't it dangerous to allow 
the user to put 5 elements in a 4 elements tab?

(tested on Linux 2.4.22 on a i686)

Thanks
