std::ifstream doesn't work with -O3 optimization

I am trying to run this code with optimization key -O3 (-O1 and O2 also do not work)

main.cpp:

#include "my_file.hpp"

int main(int argc, char* argv[]){
    test_another();

    return 0;
}

my_file.hpp:

#include <string>
#include <fstream>

void test_another(){
    std::ifstream bar;
    bar.open("C:\\Users\\ische\\source\\repos\\OpenMpCpp\\test.in");
}

What I get: "Exception has occurred. Segmentation fault" in istream file when basic_istream() is called.

If function test_another() is moved to the main.cpp file - all works fine even with -O3 key. If program is compiled without any optimization key (O1, O2, O3) then it is a successful compilation.

I use Windows10, compiler is g++ from MinGW package: g++.exe (MinGW.org GCC-6.3.0-1) 6.3.0

Anyone has any ideas why is this happening?
