Subject: [PATCH] Allow destructor to throw when building with >=C++11

After C++11, destructors default to `noexcept(true)`.  Thus, any throw statements in destructors become calls to `std::terminate()`.  To enable the intended throw statement, the destructor must be explicitly marked `noexcept(false)`.
