It was found using the following -Python configuration: - - In Python 3.6 create a directory 'debug' and cd into it. - - ../configure --with-pydebug --prefix=$HOME/pydebug/ --enable-shared - -Then a lot more refcounting errors show up, which are due to a bug in -the code position of the shutdown procedure. -The reason for the initial refcount bug was that the shutdown code is once -more often called than the creation of the qApp wrapper. -Finally, it was easiest and more intuitive to simply make the refcount of -qApp_content equal to that of Py_None, which is also not supposed to be -garbage-collected. - -For some reason, the test does not work as a unittest because it creates -no crash.
