不能只在调试中创建虚拟设备

Question

我正在制作一个vulkan渲染器，当我尝试创建一个逻辑设备时，它只在调试模式下抛出vkCreateDevice上的以下异常:

在Game.exe中的0x00007FFBA327A34B (vulkan-1.dll)抛出异常:0xC0000005:访问违反读取位置0xffffffffffffffffffff .

下面是代码(顺便说一下，这主要是按照vulkantutorial.com教程制作的):

bool FindQueueFamilies(VkPhysicalDevice device, uint32_t* indices)
{
bool found = false;
uint32_t queueFamilyCount = 0;
vkGetPhysicalDeviceQueueFamilyProperties(device, &queueFamilyCount, nullptr);
VkQueueFamilyProperties queueFamilies[512];
vkGetPhysicalDeviceQueueFamilyProperties(device, &queueFamilyCount, queueFamilies);
for (uint32_t i = 0; i < queueFamilyCount; i++)
{
const auto& queueFamily = queueFamilies[i];
if (queueFamily.queueFlags & VK_QUEUE_GRAPHICS_BIT)
{
if (indices != nullptr)
{
*indices = i;
}
found = true;
}
}
if (!found)
{
Loggers::Error("Didn't find queue family!");
}
return found;
}
...
void* RenderDevice::CreateVulkan(void* physicalDevice)
{
//Logical device
uint32_t indices = 0;
FindQueueFamilies(*((VkPhysicalDevice*)physicalDevice), &indices);
float queuePriority = 1.0f;
VkDeviceQueueCreateInfo queueCreateInfo{};
queueCreateInfo.sType = VK_STRUCTURE_TYPE_DEVICE_QUEUE_CREATE_INFO;
queueCreateInfo.pNext = nullptr;
queueCreateInfo.flags = 0;
queueCreateInfo.queueFamilyIndex = indices;
queueCreateInfo.queueCount = 1;
queueCreateInfo.pQueuePriorities = &queuePriority;
VkPhysicalDeviceFeatures deviceFeatures{};
VkDeviceCreateInfo createInfo{};
createInfo.sType = VK_STRUCTURE_TYPE_DEVICE_CREATE_INFO;
createInfo.pNext = nullptr;
createInfo.flags = 0;
createInfo.queueCreateInfoCount = 1;
createInfo.pQueueCreateInfos = &queueCreateInfo;
createInfo.enabledExtensionCount = deviceExtensionsCount;
createInfo.ppEnabledExtensionNames = deviceExtensions;
createInfo.pEnabledFeatures = &deviceFeatures;
VkDevice device;
if (vkCreateDevice(*((VkPhysicalDevice*)physicalDevice), &createInfo, nullptr, &device) != VK_SUCCESS)
{
Loggers::Error("failed to create logical device!");
}
VkQueue graphicsQueue;
vkGetDeviceQueue(device, indices, 0, &graphicsQueue);
return &device;
}

对我来说，你的意思是physicalDevice而不是*((VkPhysicalDevice*)physicalDevice)，因为这是vulkan-turorial.com使用的，这也是我在渲染中使用的。这是你的问题吗?还要记住，访问冲突可能是由坏指针引起的。
