New submission from Enric <len...@gmail.com>:
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.
A fix for that macro seems to have been committed to master:
