Using shared_ptr and glutInit causes segmentation fault - c++

Question

Having asked this before I tried out a lot of things and found out that the problem has to do with glutInit. Take the following code examples:
main.cpp
#include <iostream>
#include <memory>
#include<GL/glut.h>
using namespace std;
int main(int argcp, char **argv)
{
shared_ptr<double> abc;
glutInit(&argcp,argv);
cout<<"Hello!"<<endl;
return 0;
}
compiled with:
g++ -std=c++11 -g -Wall -o appx main.cpp -lGL -lGLU -lglut
cause the executable to instantly crash (no "Hello!" output) with segfault using g++ 5.2.1, ubuntu 15.10
Just commenting out the line
shared_ptr<double> abc;
will fix the crash.
Since i want to use shared_ptr and glut in a project I would like to know how this can be fixed or what causes the crash.

Answer 1

As posted in the comments the problem was similar to the problem posted here.
The solution is adding:
-lpthread
to the compiler flags!
Thanks a lot!
