This happens on a 32-bit build on a 64-bit system, which happens to have some interesting properties: for example, malloc() will happily allocate memory larger than Py_SSIZE_T_MAX. The crash is exactly triggered by the following snippet: if sys.maxsize < (1 << 32) and struct.calcsize('P') == 4: self.assertRaises(OverflowError, self.marshal(b'\ta\n\tb').expandtabs, sys.maxsize)
