4652,is_wrapper<std::string> assertion failed in xml_archive case,kondo@…,Robert Ramey,"When I serialize a class that includes std::string non intrusively, below error occurred.

'boost::mpl::assertion_failed' : Cannot convert 1st argument 
'boost::mpl::failed ************boost::serialization::is_wrapper<T>::* ***********'
to 'boost::mpl::assert<false>::type'.

T=const std::string

The error occurs only when I use the xml_archive. The text_archive has no problem.

I tried to fix my code. And I add below code.
{{{
BOOST_CLASS_IS_WRAPPER(std::string)
}}}
The error doesn't occur.

But I don't understand why should I use this macro. I guess it should care in the serialization library.


I attached the simple example to reproduce this problem.
