Rendering the standard cube in Blender 2.79 with CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 results in the following assertion failure:

ASSERTION FAILED: (isa<AllocaInst>(ptr) || ptrCandidate.empty()) && "storing/loading pointers only support private array"
  at file /home/sa/Downloads/beignet/beignet-1.3.2/backend/src/llvm/llvm_gen_backend.cpp, function void gbe::GenWriter::findPointerEscape(llvm::Value*, std::set<llvm::Value*>&, bool, std::vector<llvm::Value*, std::allocator<llvm::Value*> >&), line 1004
