That's probably because of the __SUNPRO_CC workaround at addressof.hpp line 110: #if (defined( __BORLANDC__ ) && BOOST_WORKAROUND( __BORLANDC__, BOOST_TESTED_AT( 0x610 ) ) ) || defined( __SUNPRO_CC ) return boost::detail::addressof_impl<T>::f( v, 0 ); #else return boost::detail::addressof_impl<T>::f( boost::detail::addr_impl_ref<T>( v ), 0 ); #endif ....

Thanks Peter, Exactly, this is the reason for addressof_test2.cpp test's failure with Oracle Studio 12.4 compiler. The only issue here is that there is 5 months old opened bug with proposed fix to cure this: https://svn.boost.org/trac/boost/ticket/10311 I'd really appreciate it if someone will pay attention to this bug, and will insert proposed simple 1 line fix in trunk area. Thanks, Sergey
