简单的 libcurl 应用程序 - 段错误

我无法弄清楚我的代码在哪里出现段错误？

基本上，它通过SSL（HTTPS）安全连接连接到服务器并进行GET，提供MachineID（程序将其作为参数）。

还应设置一些自定义标头。然后，我将返回的正文和标头保存为单独的文本文件。（基本上它将运行一个shell脚本，因此我的远程系统可以自动从我的服务器获取"订单"）

但它存在段错误，我唯一必须开发的 Linux 机器是我的 VPS，由于它们奇怪的虚拟化，加载 GDB 总是崩溃...... ：o

谁能告诉我问题出在哪里？ - 我认为它几乎可以肯定在我的字符串连接中 - 我在那里建立标头并请求 URL。

编辑：呃，忘记密码了！
