I can't reproduce it with the example from manual. It's obviously a ctypes problem, that's one of the issues I haven't been able to solve, although I thought this comes up only with Python 3, not 2. That's why I wanted to branch 7.6 first because I knew it might take some time to get these problem fixed in trunk.
