[New-bugs-announce] [issue27662] Check against PY_SSIZE_T_MAX instead of PY_SIZE_MAX in List_New

[Xiang Zhang]

New submission from Xiang Zhang:

List_New checks against PY_SIZE_MAX. The upper bound of PyMem_Malloc is PY_SSIZE_T_MAX.

Instead of simply changing the constant, another method is delegating overflow check to PyMem_Calloc, so we can avoid the check in unnecessary check in PyMem_Malloc. But I am not sure hiding the check in PyMem_Calloc is a good idea or not.
