For the record, building with ICC gives the same behavior of GCC. Let's ask
Jason' opinion about this.

------- Comment #6 from jason at gcc dot gnu dot org  2010-09-02 00:24 -------
This is standard-conformant behavior.

15.3/15: "The currently handled exception is rethrown if control reaches the
end of a handler of the function-try-block of a constructor or destructor."

The rationale for this is that the object has not actually been created, so
trying to continue as though it had been would cause problems.

Ah, ok, that makes good sense.  Thanks for the clarification.
