Antoine Pitrou added the comment: The crash is very obscure, I don't think we want to bother with a unit test for that (it took 14 seconds to crash or pass here). > This might help notice that comparing an integer of type Py_ssize_t to > check if it's greater than PY_SSIZE_T_MAX is bogus in C

Armin Rigo added the comment: You may want to add a test. This might help notice that comparing an integer of type Py_ssize_t to check if it's greater than PY_SSIZE_T_MAX is bogus in C :-( -- resolution: fixed -> stage: committed/rejected -> test needed

New submission from Armin Rigo: Run this example on a 32-bit machine with more than 2GB of addressable RAM (e.g. by default, more or less anything but Windows). On Python 2.7 it raises "SystemError: Negative size passed to PyString_FromStringAndSize". On a debug version, it causes an assert i
