| oh, that was me. I added new tests and sanitizer line when I noticed new 
| test need it. I did not realize it would affet existing tests. Let me push 
| the two tests.

Thanks.  I was worried that this intermediate state had been intentional.

I certainly accidentally break some tests from time to time.
I aspire not to.
