Summary: freed pointer is used in longobject.c:long_pow()
Initial Comment:
See in the following code snippet (from the end of the
long_pow function in longobject.c) that "b" is used
after it has been freed:
Done:
Py_XDECREF(a);
Py_XDECREF(b);
Py_XDECREF(c);
Py_XDECREF(temp);
if (b->ob_size > FIVEARY_CUTOFF) {
for (i = 0; i < 32; ++i)
Py_XDECREF(table[i]);
}
return (PyObject *)z;
}
The error exists in 2.4.1 and on CVS trunk.
