What I also meant to say, is that debug Python is not affected, and this had me
deeply confused. Any ideas how that could happen?

New submission from Kay Hayen :
Hello,
in trying to know what to put into "__annotations__" at run time, the "from
__future__ import annotations" pose a new problem. It is now necessary to
"unparse" to ast code that is still there.
Code to do so, is in C A
Kay Hayen added the comment:
So I was confused indeed.
Actually I am observing in other tests at least, that apparently Nuitka
compiled execution in my tests can import _testcapi module, which normal
execution of the test does not manage.
Then there is the possibility that the exit code
Kay Hayen added the comment:
I think that the whole reason I was doing this, is because with "os.execl" on
Windows, the exit code was always lost, but of course it is very important and
"subprocess.call" promises to return it.
I just tried if 3.7 has any better exit

Thanks for pointing out, where it comes from, Serhiy.
So, should the test case be removed then. I still am not so sure about
