This is an issue with glslc, is there a way for you to update that?

[lazka]

I'm seeing the same error with the latest glslc release from shaderc v2025.2

$ glslc  --version
2025.2
3~1.4.313.0
15.2.0

Target: SPIR-V 1.0

[jeffbolznv]

I think this is the issue I fixed in KhronosGroup/glslang#3911. Can you try with one of the latest builds from https://github.com/google/shaderc/?tab=readme-ov-file#downloads?

[lazka]

Thanks! I can confirm that updating glslang to 15.3.0 and then rebuilding shaderc fixes things.

[celan69]

Can independently confirm that the fix by @jeffbolznv and its integration into the MSYS2 packages by @lazka work! Thank you guys for your quick resolution of this issue!

[DickyQi]

fixed it since update gosling👍
