// One day, if we're lucky, this test will start failing by emitting SIL
// instead of diagnosing an error. If you are reading this comment because that
// joyous day has finally arrived, please remove the "not" in the RUN line.
// Until then, we will at least make sure we don't regress and start crashing
// again.
