With the minimal test:

#include <boost/tr1/memory.hpp>
int main() {}

I am getting the following using gcc 4.7.2 in C++11 mode:

/usr/local/boost/boost_1_53_beta/include/boost/shared_ptr.hpp:17:0,
                from
/usr/local/boost/boost_1_53_beta/include/boost/tr1/memory.hpp:56,
                from test.cc:1:
/usr/local/boost/boost_1_53_beta/include/boost/smart_ptr/shared_ptr.hpp:782:74:
error: declaration of ‘template<class T> void
boost::swap(boost::shared_ptr<T>&, boost::shared_ptr<T>&) noexcept
(true)’ has a different exception specifier

.. and so on...

I have duplicated this behavior using clang in C++11 mode.

The problem is that template<class T> void swap(shared_ptr<T> & a, shared_ptr<T> & b) (and others) is declared BOOST_NOEXCEPT in /boost/smart_ptr/shared_ptr.hpp, and without the BOOST_NOEXCEPT in boost/tr1/memory.hpp.

With the attached patch applied, the OP's trivial program now compiles w/o errors (using clang).

I have marked this as a showstopper because I believe this needs to be fixed before the 1.53.0 release.
