Coverity is able to detect some cases of refcount leaks. I don't know if
the software is able to keep track of all reference counts. But it
understands missing Py_DECREF() in error branches.
For example:
PyObject *n = PyLong_FromLong(0);
PyObject *u = PyUnicode_FromString("example");
if (u == NULL) {
return NULL;
/* Coverity detects that 'n' leaks memory */
}
