Swap issue

// Example 1
// Does not swap values (some of them inside the braces may return 0)
my_array[i] ^= (my_array[i-1] ^= (my_array[i] ^= my_array[i-1]));

// Example 2
// Works fine, just requires more lines, although it's the exact same technique as above
my_array[i] ^= my_array[i-1];
my_array[i-1] ^= my_array[i];
my_array[i] ^= my_array[i-1];
