I expect `pickle.loads()` to raise `_pickle.UnpicklingError` for any invalid input, but for the specific example shown below, the interpreter crashes after attempting to allocate >16GB of memory. Note that this input does not have the pickle header (b'0x80'), so it should be easy to distinguish from valid input.
$ python
Python 3.8.2 (default, Apr 13 2020, 11:02:04)
[Clang 9.0.1 ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> pickle.loads(b'January 11')
