[issue18298] pythonw.exe fails with redirected stderr

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Yes, in pythonw.exe the C stderr is not really usable, and this leads to unpredictable results.
It's difficult to fix in python2 though; python3 has fixed this issue, but in a way that cannot be backported.

Some workarounds:
- don't use pythonw.exe in a console, it's meant to be a *windows* application, without standard streams. I'm actually surprised of the behavior of your first example.

- use python3, where pythonw will set sys.stderr to None, and prints will be silently discarded.
