Pointer assignment Problem

When i run the above program in gcc complier(www.codepad.org) i get the output as Disallowed system call: SYS_socketcall Could anyone please clear why this error/output comes?

int main() {
    int i=8;
    int *p=&i;
    return 0;

what i have observed is i becomes inaccessible after i execute *++p=2;WHY?


When you do *p = &i, you make p point to the single integer i. ++p increments p to point to the "next" integer, but since i is not an array, the result is undefined.
