Hi William,
I don't know precisely but in case it can help I would raise that the
main difference between step() and run() is Py_BEGIN_ALLOW_THREADS, at
least if O.run(...,wait=True).
Do you have the same problem with and without "wait"?
Simply passing to c++ a python expression (just a string with python
commands) or a python function returning a value - instead of a
derived class object - could be a simple workaround maybe.

Hi,
@Janek
Yes, I'm aware of the doc about subclassing types in python. There
are
no problem about that, since it works when calling O.step()
instead of
O.run().
@Anton
The complete backtrace is attached to this mail. Functions of
interests
are around line 400.
Best Regards,
William
