I compiled PyPy with CPython, and I got a different binary than when I

willing to venture a guess, based on what I've experienced to my own
detriment: the annotator will actually follow, annotate, and make available
for the translation anything it can get its hands on during the translation,
even if those are otherwise run-time objects.
For example, if a (non-rpython) module in PyPy creates module-level objects,
then the execution of creating those objects is traced. If that creation uses
standard python modules, then in the CPython case that is just more python,
but it may lead to loading of rpython code (as part of the standard module's
internals) in the PyPy case. That code then enters into the translation and
will show up in the final .c files.
Is there some randomness in translate.py?
Because of the above, I've had random differences, but that was a bug. :)
Best regards,
Wim
