Not introducing data races into race-free programs means not moving
writes out of conditional statements in which they appear.
For example, a compiler must not invert the conditional in this program:
</p>

<pre>
*p = 1
if cond {
	*p = 2
}
</pre>

<p>
That is, the compiler must not rewrite the program into this one:
</p>

<pre>
*p = 2

    </p>

      <code>Insert</code> now always panics if the argument <code>i</code> is out of range. Previously it did not panic in this situation if there were no elements to be inserted.
