Message 186788 - Python tracker

Hmm, forget what I just said. A SystemError can actually be triggered through a slightly longer line:

$ ./python -c "import pickle; print (repr(pickle.loads(b\"S'    \np0\n.\")))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
SystemError: Negative size passed to PyBytes_FromStringAndSize
