尝试使用Vulkan做一个最小的例子，我在终止时遇到分段错误。我发现的所有例子都非常相似，但我仍然遇到了崩溃。

尝试

#include <iostream>
#include <vulkan/vulkan.h>
int main()
{
    using std::cout;
    using std::endl;

    // Application info
    VkApplicationInfo appInfo = {};
    appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO ;
    appInfo.apiVersion = VK_API_VERSION_1_0;
    appInfo.applicationVersion = VK_MAKE_VERSION( 0 , 0 , 1 ) ;
    appInfo.pApplicationName = "test_vulkan" ;
    appInfo.pNext = nullptr;
    appInfo.pEngineName = "test_vulkan";

    // Instance info
    VkInstanceCreateInfo instanceInfo = {};
    instanceInfo.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    instanceInfo.flags = 0;
    instanceInfo.pApplicationInfo= &appInfo;
    instanceInfo.pNext = nullptr;
    instanceInfo.ppEnabledExtensionNames = nullptr;
    instanceInfo.ppEnabledLayerNames = nullptr;
    instanceInfo.enabledLayerCount =0;
    instanceInfo.enabledExtensionCount = 0;

    // Create instance
    VkInstance instance = nullptr;  
    VkResult res = vkCreateInstance( &instanceInfo, nullptr, &instance); // null is the allocator for host

    if (VK_SUCCESS==res) cout << "Instance created with success" << endl;
    else cout << "Failed to create instance" << endl;


    if (instance)
    {
        vkDestroyInstance( instance , nullptr ) ;
        cout << "Instance destroyed" << endl;
    }
    instance = nullptr;


    return 0;
}

问题

导致此分段错误的原因是什么？

电脑规格：

Debian Jessie 8.8
显卡：Nvidia 1050Ti，驱动程序375.66

Vulkan在终止时导致段故障。为什么？
