使用shared_ptr和glutInit导致分段错误 [英] Using shared_ptr and glutInit causes segmentation fault

问题描述

在我尝试了很多事情之前，我问过这个这个问题与glutInit有关。请看下面的代码示例：
main.cpp

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;
}

编译：

g ++ -std = c ++ 11 -g -Wall -o appx main.cpp -lGL -lGLU -lglut

g++ -std=c++11 -g -Wall -o appx main.cpp -lGL -lGLU -lglut

导致可执行文件使用g ++ 5.2.1，ubuntu 15.10立即崩溃（没有Hello！输出）

cause the executable to instantly crash (no "Hello!" output) with segfault using g++ 5.2.1, ubuntu 15.10

只是注释掉行

shared_ptr<double> abc;

将修复崩溃。

我想在一个项目中使用shared_ptr和glut。我想知道如何解决这个问题或导致崩溃的原因。

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.
