This is where your misunderstanding arises. Just as 5+3 can add up to the
same result as 4+4, so you cannot ignore that the final mapped addresses you
are seeing add up to the same result via different routes. Compile your
sources using --save-temps, and look at the differences in the generated
assembly files. By looking only at the final results, you are losing
information about how those results are arrived at.
cheers,
