Linux-2.4.22 memory overwriting

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
