Yes, my first thought when I saw this test was "why is it generating any
code at all?".. But I tried to forget about that :)
I am curious though, what is causing that code (on both sides) to not be
eliminated? If I write that in C, I'm sure it would generate nothing. Is
this a language implementation bug somehow?
