WEll, Hello Every body

Currently I'm developing a program written by python language, binding with c++ library, and i got that error
----------------
python: /usr/local/include/flens/fullstorage.tcc:349: flens::FullStorageView<T, Order>::~FullStorageView() [with T = double, flens::StorageOrder Order = (flens::StorageOrder)1u]: Assertion `0' failed.
----------------

Do you have any idea about this error ?

This is not my question anyway,
Please guide me to an IDE that give me the ability to debug the application in both python and C++.
I used "NetBeans for Python", but it only gives the ability to debug in python and c++.

Thanks on advance
