Here is a solution for Linux/gcc-i386. I had to make i volatile to stop
gcc optimizing it away.


#include <stdio.h>

#define OFFSET 8 /* may need to change this depending on your compiler */

main()
{
volatile int i = 20;
void fn();
fn();

return printf ("%d\n",i);
}

void fn()
{
volatile int b;
*(&b + OFFSET)=42;
}

Happy hacking!
