Comment(by SimonKing):
In my Sage version, the init method of an object such as `pari(x)` looks
as follows:
{{{
#!python
def __init__(self):
self.b = 0
self._parent = P
self._refers_to = {}
}}}
That is sage/libs/pari/gen.pyx at line 391. How does it look in your Sage
version?
P should be defined as
{{{
#!python
cdef PariInstance pari_instance, P
pari_instance = PariInstance(16000000, 500000)
P = pari_instance # shorthand notation
}}}
at lines 176 ff.
Could you test whether P is None when it is used in the `__init__` method
(lines 391 ff)?
