Indeed, using an extra zero pad byte could bump the stack frame size by 4 or 8
or 16 bytes, or could leave it unchanged, depending on alignment prior to
adding the byte and the alignment requirements of the

I doubt you could skip one byte as the protector location has to be aligned.
So the trade off is adding at least 4 or 8 bytes (depending on which ABI is
used) or 8bits less of the randomness.
