NSIndexSet.alloc().initWithIndex_ segfaults

[Sbte]

Describe the bug

The following code segfaults:

from Foundation import NSIndexSet
s = NSIndexSet.alloc().initWithIndex_(0)

This is used in array_property so using array_property also causes segfaults.

Note that NSIndexSet.indexSetWithIndex_(0) works fine.
