// This causes the register used by the call in the later try-catch block to be
// used by the ToName conversion for null which causes a DCHECK fail when
// compiling. If register allocation changes, this test may no longer reproduce
// the crash but it is not easy write a proper test because it is linked to
// register allocation. This test should always work, so shouldn't cause any
// flakes.
