C++ 11 Boost 1.65 recursive_directory_iterator giving segmentation fault error

My code below kept running into segmentation fault error and i can't seem to figure out why. Help pls~~ My goal is to read a folder and all of its subfolders to find all files ending with extension ".txt" so i am using boost's recurisve directory iterator to help achieve the task. This issue arrived suddenly as my code was running fine last week.

test.cpp:

#include <sstream>
#include <iostream>
#include "/home/dj/boost_1_65_1/boost/filesystem.hpp"
using namespace std;
int main()
{
    using namespace boost::filesystem;
    recursive_directory_iterator end;
    for (recursive_directory_iterator it("./"); it != end; ++it)
    {
        std::cout << *it << endl;
    }
    return 0;
}

i am running on Linux and i compile my test.cpp with boost 1.65 as static :

g++ -g -I /home/dj/boost_1_65_1 test.cpp -static -static-libgcc -o delete -static-libstdc++ -std=c++11 -L/home/dj/boost_1_65_1 -lboost_filesystem -lboost_system

with gdb and some cout i found that error came from the line below.

for (recursive_directory_iterator it("./"); it != end; ++it)

somehow when i call for "recursive_directory_iterator", my system crashes giving this error

Program received signal SIGSEGV, Segmentation fault.
0x00000000004f1c8b in memcpy ()

the exact same error persists even if i reduce the code to

int main()
{
    using namespace boost::filesystem;
    recursive_directory_iterator it("./");
    return 0;
}
