This is a general bug in the derived-to-base destructor alias optimization. 
We're doing the optimization even when we only have a declaration of the target
destructor in this translation unit — which is to say, we're emitting an alias
to an unresolved symbol, which isn't representable in any object file format I
know of.  Apparently the symptom is that alias just gets dropped at some point.

Fixed in r97637.
