[issue23363] integer overflow in itertools.permutations

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

An overflow in n * sizeof(Py_ssize_t) is not possible because n is the length of already allocated array of pointers.

+        with self.assertRaises(OverflowError):
+            permutations("A", 2**30)

The test needs 4GiB. May be use 2**29?

+        with self.assertRaises(OverflowError):
+            permutations("A", 2, 2**30)

permutations() takes at most 2 arguments.
