I have exactly the same build on Windows and get the expected 9.

Try it again.

i know, idid try it again and it works as expected. but how the h***
did it not work that one time?

Maybe the interpreter remembered the values of some objects you used?
If you type in the interpreter, the objects you create have a lifetime
as long as the interpreter is active, which means it can get a state
behaviour that otherwise is not present if you start a new interpreter
instance. To be safe you should always try it with a script and run it
from the commandline to get the same 'state' everytime your script
runs.
