Current comment in Objects/dictobject.c:
/* We can arrive here with a NULL tstate during initialization: try
running "python -Wi" for an example related to string interning.
Let's just hope that no exception occurs then... This must be
_PyThreadState_GET() and not PyThreadState_Get() because the latter
abort Python if tstate is NULL. */
PyDict_GetItem() is no longer called before Py_Initialize(). I reworked the
Python startup to no longer use Python objects before Py_Initialize(): see PEP
587 (PyConfig).

Hum, since the whole test pass with the change and it was not documented that
it was possible to call the function with the GIL released, I changed my mind
and only kept the runtime check in debug mode.
