for a code example:
```
v = []
b = bytearray(0xffff)
for i in range(2**31+1)
# the ob_exports would be overflow in 32 bit machine when i = 2**31.
v.append(memoryview(b))
```
IMHO, i thought converting the type of ob_exports to Py_ssize_t is fine.
PS: I have no actual user scenario.

sorry, typo error. # the ob_exports would be overflow in 32 bit machine when i = 2**31. --> # the ob_exports would be overflow in 64 bit machine when i = 2**31. |
