It looks like this could relate to https://github.com/KhronosGroup/SPIRV-LLVM-Translator/issues/481 see also https://github.com/JuliaGPU/oneAPI.jl/issues/55 I don't know why the change to gcc12 seems to have caused this to suddenly be a problem.
There's a few possible options. Since gcc11 is the default for 22.04, I can see that it might make the most sense to use this version in the CI. It is unfortunate that currently gcc12 is required to build rocm on 22.04 https://github.com/ROCm/ROCm/issues/2949 which motivated this uplift.
If desired I could change the docker image to use gcc12 only when building rocm (but not dpc++). I think this is likely to work. I suppose another alternative would be to skip gcc12 and try gcc13.
It does seem like there may be an underlying spirv issue though that someone may want to look into: https://github.com/KhronosGroup/SPIRV-LLVM-Translator/issues/481 I imagine you will want to support gcc12.
Also since the nightly has been broken for a while, the uplift to gcc12 may have nothing to do with this spirv issue. I suppose I could confirm this by changing back to the previous image that didn't use gcc12/updated rocm. I will try some things locally in the docker.
