I'd say that the solution should also work for the other situations 
(at least dynamic_cast on reference can throw). This somewhat rules
out the two first solutions proposed by Nathan.

In addition to the pedwarn, maybe there should be specific versions
of the generated code (functions) that implement new or dynamic_cast.
The code would print a message and call abort(). This is 
consistent with the behavior we have when calling pure methods.
