In PyTuple_New, if the new tuple won't go on the free_list:
/* Check for overflow */
if (nbytes / sizeof(PyObject *) != (size_t)size ||
(nbytes > PY_SSIZE_T_MAX - sizeof(PyTupleObject) - sizeof(PyObject *)))
{
return PyErr_NoMemory();
}
nbytes += sizeof(PyTupleObject) - sizeof(PyObject *);
nbytes is never used after the overflow check, so the last addition is a waste.

There is no such code in current sources. |

The line "nbytes += " was removed 5 years ago by the changeset 7be8129ee0fd. It's maybe time to update your Python version? :-) Only Python < 2.7 has the line, it was removed before Python 2.7.0 was tagged. |
