Comment (by robtoth@…):

 Sorry but I still can't compile this. The const is fine and I understand
 it, but the "friend" doesn't help.

 ''boost_serialize_protected_bug_minimal_2.cc:''
 {{{
 ...
 class Base1{
 friend class boost::serialization::access;
 friend class Derived; // Added this
 ...
 }}}

 I still get the error:

 {{{
 include/boost/serialization/smart_cast.hpp:204: error: 'Base1' is an
 inaccessible base of 'Derived'
 }}}

 This is on gcc svn trunk (2013-01-22, version 4.8) and boost svn trunk (as
 of 2013-01-22, version 1.53.0).

 Did you do something different from what I did to make Derived serialize?

 I can attach the full error output if it would help.
