I think your correct. There is a bug and your fix addresses it. I'm still looking at this. Robert Ramey Marco Jez wrote:

Hello, I'm still having troubles with Boost.Serialization in Boost 1.41. The following example code fails to compile with latest Boost release, while it works with 1.39:

#include <boost/archive/binary_iarchive.hpp> #include <boost/serialization/shared_ptr.hpp> #include <boost/shared_ptr.hpp> #include <iostream>

// dummy struct with no actual serialization code struct Test { template<typename A> void serialize(A &, unsigned) {} };

int main() { boost::archive::binary_iarchive ia(std::cin);

boost::shared_ptr<Test> x; ia & x;

return 0; }

The compiler (MSVC 9) gives me this error: error C2440: 'return' : cannot convert from 'const boost::serialization::extended_type_info_typeid<T>' to 'const boost::serialization::extended_type_info *'c:\boost\include\boost-1_41\boost\archive\shared_ptr_helper.hppIt seems that an address-of (&) operator is required in shared_ptr_helper.hpp at line 111, that is: ... return boost::serialization::singleton< ...

should read:

... return &boost::serialization::singleton< ...

This change makes my code compile, but I'm not sure whether it's an appropriate fix or not, as I don't know Serialization's internals.

Cheers, Marco
