Vulkan driver access violation in vkCreatePipelineLayout

[maxime-modulopi]

OS: Windows 10 64-bit

GPU: Arc A770

Driver: 32.0.101.6460

Problem:

The driver may crashes with an access violation when calling vkCreatePipelineLayout.

This happens when a descriptor set layout referenced by this pipeline layout was created with PUSH_DESCRIPTOR + a pNext chain in its VkDescriptorSetLayoutCreateInfo.

This seems to indicate that the driver does not properly copy the pNext chain when vkCreateDescriptorSetLayout is called.

I have attached a sample file that reproduces the crash.

I used vk::DescriptorSetLayoutBindingFlagsCreateInfo in the sample but it also crashes with other structs such as vk::MutableDescriptorTypeCreateInfoEXT.

Note that the crash does not happen if validation layers are enabled, presumably due to more forgiving CreateInfo structs lifetime in these layers.

Hello maxime-modulopi,

Thank you for sharing this information and for posting in the community. I have a few questions to better understand the situation:

1. Can you tell me what GPU you are using?
2. What was the current graphics driver version when you tried this?
3. Does this issue also occur when using different driver versions?

Also, to better understand your entire system information, please use the System Support Utility (SSU). This will generate a text file that compiles all your system information. You can follow this link for instructions and send the text file here: Help Guide for the Intel® System Support Utility

Hello Dhanniel,

1) and 2) are already specified in my initial message.

3) Yes, I've had obscure driver crashes in vkCreatePipelineLayout when using push descriptors on the Intel driver for a few years at least.

I do not have access to the Intel card today but I can send you the SSU report tomorrow if needed.

I also forgot to mention that the crash happens when the structs passed in the pNext chain are freed after the vkCreateDescriptorSetLayout call, but before the vkCreatePipelineLayout call, which is valid according to the Vulkan specs as the driver is not allowed to accesses the input structs after the vkCreate* calls.

Hello maxime-modulopi,

Apologies for that I overlooked that in the post. Sure I will be waiting for the SSU tomorrow.

Hello Dhanniel,

I have attached the report.

I just realized that I specified the wrong OS in my initial post.

It's Windows 11, not Windows 10.

Hello Dhanniel,

I am a graphics programmer at Modulo Pi, a media server company.

We are not related to game development at all.

Hello Karen,

Thank you for investigating this issue.

I added in this reply an important information that I forgot to add in the initial post.

I just want to make sure you didn't miss this information as without it, you might have trouble reproducing the issue.
