Access violation in glLinkProgram

Dennis_SHD — Tue, 12 Dec 2023 13:19:15 GMT

Hi,

I get an access violation on glLinkProgram with the attached Vertex and Fragment Shader. Both shader compiles successfully with glCompileShader.

The Shader Code is converted from SPIR-V Vulkan Shaders with SPIR-V Cross (Vulkan 1.3.261.1).

System:

CPU i7-10750H

Windows 10 Pro 64-bit

OpenGL Info:

Vendor: Intel
Renderer: Intel(R) UHD Graphics
Version: 4.5.0 - Build 31.0.101.2125

Kind regards

Dennis

The Shaders are used for Screen Space Reflection as part of our rendering engine. The rendering engine is used in a commercial planning software for Windows written in C++.

On other Graphic Hardware (testet with mutliple cards from Nvidia and AMD) everything works as expected.

Hello, @Dennis_SHD

Thank you for your reply.

Are you working for a company or are you the developer (independent)?

What is the name of the company?

Are you able to share the application/software you are working on? We can send you an email associated with your community profile if needed.

If it is not possible, then please provide us with the following important information we need to investigate:

Replication steps to reproduce this issue, please be specific as this is important to perform the correct investigation.

The name of the company is "SHD AG".

I cannot share the source code of our software, but I created a minimal example. The attached archive contains a crash dump of the minimal example, the associated executable and source code (main.cpp).

The needed external dependencies are glfw3 for OpenGL context creation and glew for OpenGL function loading (Used versions are also included in the archive).

Best regards,

Dennis

Hello, @Dennis_SHD

Thank you for your time.

Please provide detailed instructions on how to reproduce this issue and test it on an 11th gen or newer system (please try using a system with the most recent CPU gen, if possible).

On the other hand, please be aware that in the scenario we find this issue is caused by our driver and develop a fix, this fix will be only available in the driver for 11th gen and newer systems.

Best regards,

Hello , @Jocelyn_Intel

Sorry for my late reply, there were holidays in Germany.

The same error also occurs with a newer notebook.

Processor: 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz, 2304 Mhz, 8 Core(s), 16 Logical Processor(s)

Driver Version: 31.0.101.5084

A minidump from this system is attached. To reproduce it start the exetuable in the previous uploaded zip archive (x64/Release/IntelAccessViolation.exe), or compile your own C++ project with the included main.cpp and external dependencies.

Best regards,

Dennis
