OBJECT_nonzero may be called with misaligned pointers, manifesting as a -fsanitize=alignment failure. This is UB per C11 6.3.2.3
Nevertheless, Clang only checks alignment when the unaligned pointer is accessed. https://lists.llvm.org/pipermail/llvm-dev/2016-January/094012.html Call memcpy with unaligned arguments instead to work with new Clang (llvm/llvm-project#67766).
