--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
In C++11 destructors have an implicit noexcept, so the 4.7 behaviour is wrong:
the program should call std::terminate() when the exception leaves ~A()

If you change the program to:

    ~A() noexcept(false)

then it runs and exits normally.

If you explicitly add:

    ~A() noexcept(true)

then you get the same behaviour from 4.7 and 4.8, it segfaults in the terminate
handler.
