Some good info is here:

=========================================
#include <stdio.h>
#include <stdlib.h>
#define x_moved(pos) ((int*)&x[pos])[0]
static const int value1 = 0x01234567;
static const int value2 = 0x89abcdef;
int main() {
volatile char *x = (char*)malloc(sizeof(int) * 2);
x_moved(0) = value1;
x_moved(2) = value2;
if (x_moved(2) != value2) {

} else {
printf("Value: ");
}
printf("%x %x\n", x_moved(0) , x_moved(2));
free(x);
return 0;
}

This results in:
ERROR Value: 89abcdef cdef89ab
