I no longer have access to the system where it was failing, so I can not reproduce it anymore.
The issue remains that the package is using the wrong API and the upstream maintainer seems to be MIA. Since about Python 2.0, PyObject_Del, not PyMem_Del, is the correct API for most users of the Python C API. If PyMem_Del happens to be working, it's an undocumented accident.
