The AMD Vulkan Beta Driver crashes with an access violation when the pApplicationInfo member of the VkInstanceCreateInfo struct passed to VkCreateInstance is NULL. However the Vulkan 1.0 spec​ states that pApplicationInfo may be NULL. So I believe this to be a bug in the current AMD driver. Can someone from AMD please confirm this and pass this on to the driver team?

Exception Message:

Can confirm the crash on vkCreateInstance when the pApplicationInfo member is null.

From Vulkan 1.0 spec:

• pApplicationInfo is NULL or a pointer to an instance of VkApplicationInfo.

Can confirm this issue. Creating a VkApplicationInfo object and assigning it to pApplicationInfo member of the VkInstanceCreateInfo fixes it.

Can you try reproducing this issue with the latest public driver, please?
