No, I don't think it does stop working, although it seems so ;-)
It is difficult to test inproc (DLL) com servers implemented in Python
with Python as the exe client.  There is no isolation between the client
and the server - both use the same interpreter.

What you see is probably a flaw in the ctypes.com server implementation
- it redirects sys.stdout/sys.stderr to somewhere else (look into
ctypes\com\server.py).

You should either use different Python versions for the client and the
server, or use normal Python for one and a debug compiled Python for the
other, or - maybe that's the best and easiest - use an EXE COM server
for testing.  Since the exe server is a separate process, the isolation
is perfect.
