The test seems to check that __cxa_vec_delete deallocates the vector even if one of the destructors throws. The call to `__cxa_vec_delete3` is not called because `__cxa_vec_delete2` is expected to throw. To check this `assert(false)` is now used instead of the side effects of `__cxa_vec_delete3`.

@mclow seems to have written the test so I'll ask him to sign off on it.
