It explicitly shows that at least Ubuntu clang version 13.0.0-2 with -01 doesn't do anything about the padding bytes (and that's after testing only 2 different compilers). Even if those compilers didn't show any problem, we still couldn't rely on an undefined behavior and assume that no other compilers behave differently.
