Hi Victor,
Thank you for clarifying.
If the call to PyCFunction_New is done from a C extension module, is it also
necessary to call Py_Initialize()?

New submission from Enric Tejedor Saavedra :
Attached is a reproducer that calls PyCFunction_New. The reproducer runs
normally with Python 3.6.5, but it crashes with Python 3.7.1. The reason seems
to be that the _PyObject_GC_TRACK macro ends up being called and it is broken
in Python3.7.
