Bug 916313 – media-libs/vulkan-layers-1.3.261: validation layers crash when using specialization constants

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description darkstalker 2023-10-26 23:11:50 UTC]

Validation layers crash when compiling a shader that uses a specialization constant value as an array size. Program works fine when validation is turned off.

It's the exact problem reported here: https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/6370
The issue shows as fixed, so it's probably fixed on next release.

Reproducible: Always

Steps to Reproduce:
1. Run the test code with validation layers enabled

Actual Results:  
The program crashes inside validation layers:

Seems like it should be fixed in the next sdk release, but upstream doesn't know which PR fixed it.
