boost::archive::xml_iarchive Exception in destructor: "input stream error-No error"

[Andrei Bryleuski <andrey-brilevskiy@…>]

The sample code:

#include <unordered_map> #include <boost/serialization/unordered_map.hpp> #include <boost/serialization/vector.hpp> #include <boost/serialization/nvp.hpp> #include <boost/archive/xml_oarchive.hpp> #include <boost/archive/xml_iarchive.hpp> #include <fstream> #include <iostream>

std::ifstream ifs("commandKeyToAction.xml"); auto newCommandKeyToAction = std::unordered_map<std::string, std::unordered_map<std::string, std::vector<std::string>>>();

boost::archive::xml_iarchive xmlIn(ifs); xmlIn >> boost::serialization::make_nvp("options", newCommandKeyToAction);

[Andrei Bryleuski <andrey-brilevskiy@…>]

File to deserialize

[Andrei Bryleuski <andrey-brilevskiy@…>]

The exception occurs in: boost_1_66_0\boost\serialization\throw_exception.hpp

template<class E> inline void throw_exception(E const & e){

throw e;

}

probably a duplicate of #13354

[Frédéric Devernay <frederic.devernay@…>]

found the problem. This is actually not a bug in boost but a bug in the code that produced the xml: the </boost_serialization> tag is missing.

maybe you used a stringstream as in #13354, and forgot to destroy the xml_oarchive before getting the string? see comment 4 in issue #13354
