I am sorry but I don't understand. What do you mean by a proper test? This test is a simplification of the original test that was breaking. Without my change it will break the same way, and and with my change it will not crash and run to completion. The comment was added to show why the test was added. I also added some CHECK tags with the tests, to make sure it is executing.
