<pre>The current error message is:
note: read of object outside its lifetime is not allowed in a constant
expression
It would be more helpful if, instead of just telling me it is outside of the
lifetime, it told me whether it was before its lifetime has begun or after it
has ended. I was very confused when I got this as I was obviously not reading
an object after its lifetime had ended, but then I realized I had misused a
cast to derived in a constructor and I was actually using it before it was
constructed.</pre>
