[New-bugs-announce] [issue7080] locale.strxfrm raises MemoryError

[egreen]

New submission from egreen <egreen at operamail.com>:

The strxfrm function in the locale module can potentially raise a
MemoryError.

The failing malloc is in Modules/_localemodule.c, line 291.

This is because the variable n0 of type Py_ssize_t is passed to
PyArg_ParseTuple, which expects an int when PY_SSIZE_T_CLEAN is not defined.

Patch attached, which also fixes an unrelated memory leak.
