This is a simple issue of lifetime management. The C++ 'a' objects
created in mk_tst are owned by their corresponding Python objects,
which get destroyed when mk_tst exits. The pointers you have stored
in your 'tst' object are dangling thereafter.
The Introduction section at
explains this fairly well
