The following test code segfaults on Python 2.7:
```python
import io
class X(io.RawIOBase):
def readable(self):
return True
def readinto(self, b):
if isinstance(b, memoryview):
print(b.format) # XXX boom, crashes here.
return 0
io.BufferedReader(X()).read(8)
```
The crash happens on the b.format attribute access.
This does not happen on 3.6.
