The code that makes me wonder something is wrong is this one:

For me (win32, FPC 2.6.2) the output is identical (= "A") whether

Result in TheA() is initialised manually or not. Perhaps 2.7.1 has a
regression here if it differs for you?
The problem is not the different behavior as it is or will be noted
in documentation, the problem is the lack of warning of using a not
initialized variable,
FPC 2.6.2 does give a warning (code is from http://bugs.freepascal.org/view.php?id=20907#c55064
):

so it is hard to fix code that works fine in 2.6.x and that could
fail with Trunk.
It could also fail in 2.6.x, just less often.
