        <pre>This is working as intended.  A read from uninitialized memory has undefined
behavior.  When a program runs into undefined behavior, anything can happen. 
The optimizer detects that the condition is only evaluated after undefined
behavior has happened.  Because of that, it removes the if-branch and executes
the else-branch unconditionally.</pre>
