Yes, on IRC Bruno already pointed out the problem with the comment 3 example.
That doesn't change my mind, I still think it would be madness for an
defaulted-on-first-declaration trivial destructor to

Clang fails this test, because memcpy overwrites the tail padding:

The meaning of "user-declared" in C++03 is closer to "has a function body" than
the meaning in C++11, where it includes defaulted definitions.
A defaulted definition in C++11 is equivalent to an implicit
