My attempt to compile failed. See below.

When I tried to compile this release candidate the compilation failed:

libs/serialization/src/archive_exception.cpp: In constructor 
'boost::archive::archive_exception::archive_exception(boost::archive::archive_exception::exception_code, 
const char*, const char*)':

declared in this scope

not declared in this scope

Currently I have no problems with 1.49.0.

The change that is causing the problem seems to be 
boost/archive/archive_exception.hpp.  In a quick comparison, it appears 
that char m_buffer[128] is supposed to replace std::string m_msg.
