[Boost-users] Serialization of optional<std::string>

As part of upgrading a product to a later version of boost the compilation has tripped up on serialization of a boost::optionalstd::string. The /optional.hpp/ header now has the comment: ...and this fires for std::string. What, if any, is the recommended way forward for this? An example code snippet to illustrate: Previous version of boost: 1.50; new: 1.6x Compiling with g++ 4.6.4 (although same problem with 4.8.5): -W -Wall -std=c++0x... (The real code is actually using the portable_binary_archive, but let's avoid muddying the waters at this stage :) -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html
