11204	undefined behavior sanitizer complains about runtime_error thrown in serialization/singleton.hpp before main()	Georg Sauthoff <mail@…>	Robert Ramey	"How to reproduce:

{{{
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/vector.hpp>

#include <vector>
#include <fstream>

using namespace std;

struct Data {
  vector<int> v;
};

namespace boost {
  namespace serialization {

    template<class Archive>
      void serialize(Archive & a, Data &d, const unsigned int version)
      {
        a & d.v;
      }

  }
}

int main(int argc, char **argv)
{
  if (argc > 10) {
    ifstream f(""/dev/null"");
    boost::archive::text_iarchive a(f);
    Data d;
    a >> d;
  } else {
    ofstream f(""/dev/null"");
    boost::archive::text_oarchive a(f);
    Data d;
    a << d;
  }
  return 0;
}
}}}

Compile via:

{{{
$ g++ -g -std=c++11 -I/home/juser/src/boost/modular-boost \
   -L/home/juser/src/boost/modular-boost/stage/lib \
   -Wl,-R/home/juser/src/boost/modular-boost/stage/lib \
   -fsanitize=undefined  test_serialize.cc \
   -o test_serialize -lboost_serialization
}}}

(GCC's undefined behavior sanitizer is enabled with {{{-fsanitize=undefined}}})

Run:

{{{
$ ./test_serialize
}}}

Expected output:

{{{
}}}

(nothing)

Actual output:

{{{
