#7627: Problem with auto_buffer implementation

 There is problem with auto_buffer implementation, in one of the
 constructors implementation "size" has been used mistakenly to calculate
 buffer's size. Please have a look at the problem area snippet below,

         auto_buffer( size_type size_arg, optimized_const_reference
                      const allocator_type& a )
             : allocator_type( a ),
               members_( (std::max)(size_arg, size_type(N)) ),
               buffer_( allocate(members_.capacity_) ),
               size_( 0 )
             std::uninitialized_fill( buffer_, buffer_ + size, init_value
             size_ = size_arg;
             BOOST_ASSERT( is_valid() );

 Line:std::uninitialized_fill( buffer_, buffer_ + size, init_value );
 Presumably, instead of "size", "size_arg" should have been used.

 Surprisingly this code compiles with gcc and Windows' compiler but clang
 gives an error here.
