Dear list,
how is it possible to have a class in C++ that can be extended from
python and that stores a weak_ptr to itself?
The reason why I want to do this:
- using a weak_ptr to itself does not introduce a memory leak.
- from a C++-member

Easy, I think: just like any other class you wrap. Are you aware of
boost::enable_shared_from_this? It does all of
Hi,
Briefly, when using the multiprocessing module, when exceptions are
thrown, they need to be pickleable in order to propagate, since that is
how multiprocessing passes information around.

Dear Dave, dear Jim,
thanks for your help in particular to `boost::enable_shared_from_this`
which I wasn't aware about in the beginning. Unfortunately your
solutions did not yet work.
In the meantime I figured out a different way of doing the shared
pointer from this in python. Namely, to just ma

Dave,
Here is the reduced example with only the
`boost::enable_shared_from_this` variant. The issues are all as
reported before.
