New issue 2533: Error
https://bitbucket.org/pypy/pypy/issues/2533/error
rowillia:
Minimal repro: Works in CPython, fails in PyPy -
```python
# requires rtree==0.8.3
from rtree import index
def generator():
yield (0, (0.0, 0.0, 1.0, 1.0), {'id': '1', 'polygon': 'hello'})
idx = index.Index(generator())
```
Exception in PyPy:
```

```
RTree has an issue open leading me to believe this is the real exception:
```
File "/usr/lib/pypy/lib_pypy/_ctypes/function.py", line 280, in f
return to_call(*args)
File "/usr/local/lib/service_venv_pypy/site-packages/rtree/index.py", line
713, in py_next_item
p_mins[0] = ctypes.cast(mins, ctypes.POINTER(ctypes.c_double))

while '_index' in where.__dict__:
AttributeError: 'NoneType' object has no attribute '__dict__'
```
Here is the snipped of code that's failing:
https://github.com/Toblerity/rtree/blob/master/rtree/index.py#L713
```python
darray = ctypes.c_double * dimension
mins = darray()
maxs = darray()
....
for i in range(dimension):
mins[i] = coordinates[i*2]
maxs[i] = coordinates[(i*2)+1]
p_mins[0] = ctypes.cast(mins, ctypes.POINTER(ctypes.c_double)) # Fails in
PyPy, not CPython
```
Version Info:
```
$ python -V
Python 2.7.12 (5.6.0+dfsg-0~ppa2~ubuntu14.04, Nov 11 2016, 17:08:28)
