C++ Cereal not serializing properly more than one object

I created simple class to test serialization with Cereal which is defined in main.cpp

struct someconf{
unsigned char station;
uint32_t ip_addr;
bool mnch;
bool mnch_ch;
bool tch1;
bool tch1_tg;

template<class Archive>
void load(Archive& arc){
    arc(station, ip_addr, mnch, mnch_ch, tch1, tch1_tg);
}

template<class Archive>
void save(Archive& arc) const{
    arc(station, ip_addr, mnch, mnch_ch, tch1, tch1_tg);
}
};


int main(int argc, char** argv)
{
ofstream out("archive.bin", ios_base::binary);
{
    cereal::BinaryOutputArchive oarc(out);

    someconf s1;
    s1.station=126;
    s1.ip_addr=0x7f01a8c0;
    s1.mnch=true;
    s1.mnch_ch=true;
    s1.tch1=false;
    s1.tch1_tg=false;


    someconf s2;
    s1.station=15;
    s1.ip_addr=0x00ffffff;
    s1.mnch=false;
    s1.mnch_ch=false;
    s1.tch1=true;
    s1.tch1_tg=true;

    someconf s3;
    s1.station=203;
    s1.ip_addr=0x7905a8c0;
    s1.mnch=true;
    s1.mnch_ch=true;
    s1.tch1=true;
    s1.tch1_tg=true;

    oarc(s1, s2, s3);
}

return 0;
}

and read file like this

    someconf test1,test2,test3;
{
   ifstream in("archive.bin", ios_base::binary);

   cereal::BinaryInputArchive iarc(in);

   iarc(test1, test2, test3);
}

When i write and read only one object - it works fine. All data is correct. But when i try to write and read multiple objects - only one of them is not corrupted after reading.

i tried to include other header files such as cereal/types/common.hpp i also tried to use JSONOutputArchive to see whats going on inside the resulted file. and it looks like serialization is incorrect even with JSON format.
