[issue35879] test_type_comments leaks references

[Pablo Galindo Salgado]

Pablo Galindo Salgado <pablogsal at gmail.com> added the comment:

The extra referenced happen here in Python-ast.c :

value = ast2obj_string(o->type_comment);
    if (!value) goto failed;
    if (_PyObject_SetAttrId(result, &PyId_type_comment, value) == -1)
        goto failed;
    Py_DECREF(value);

ast2obj_string increments it once and the setattr does it again and then there is only one Py_DECREF.
