Followup-For: Bug #998058 This is actually caused by the (transitive) B-D using different LLVM versions: intel-graphics-compiler is built against llvm-12, while intel-opencl-clang and spirv-llvm-translator are built against llvm-13.
This combination "only" causes some tests to fail, while other combinations (e.g. using a intel-opencl-clang rebuilt with llvm-12) can cause some compilation step to fail with "Aborted". I'm working on updating the packaging of the whole stack s.t. the dependencies only allow for a consistent llvm usage ;-) Andreas
