In PyCXX I allows exceptions to go into and out of python and C++. https://cxx.sourceforge.net/ You can raise in C++ go into python and back into C++ and the exception arrives as expected. You can riase in Python fo into C++ and back to Python and again the exception arrives as expected. That is as long as its a python exception.
