The C++ code uses new to create an object on the heap, which you must delete later In python if nothing references the object, it is destroyed. So as soon as __init__ is done, job goes *poof* You need to maintain a reference to it by using self.job = ... so that way the class keeps the job instance around.

Jeg har intet at gøre med FARC, al-Jihad, al-Qaida, Hamas, Hizb al-Mujahidin eller ETA. Jeg har aldrig gjort Zakat, går ikke ind for Istishad, har ikke lavet en bilbombe eller kernevåben og jeg ved dårligt nok, hvad Al Manar og бомба betyder.
