bug during compilation for CPU

[AuroraPerego]

When compiling the SYCL version of pixeltrack-standalone for the CPU backend with the 20230613 nightly, it crashes during the compilation of gpuVertexFinder.cc.
This DIDN'T happen with oldest nightlies (20230309 the latest tested).

Backtrace:

clang-17: /data/user/fwyzard/sycl/llvm/llvm/include/llvm/IR/Instructions.h:972: static llvm::GetElementPtrInst* llvm::GetElementPtrInst::Create(llvm::Type*, llvm::Value*, llvm::ArrayRef<llvm::Value*>, const llvm::Twine&, llvm::Instruction*): Assertion `cast<PointerType>(Ptr->getType()->getScalarType()) ->isOpaqueOrPointeeTypeMatches(PointeeType)' failed.
PLEASE submit a bug report to https://github.com/intel/llvm/issues and include the crash backtrace, preprocessed source, and associated run script.
