The first one was real.

The second one I'm not sure. I can't reproduce it on gcc and maybe it's related to clang optimization or their specific STL's list implementation (I doubt so). I have pushed a commit to bugfix/issue-1902 branch that maybe fixes the problem. But I used that idiom a number of times, so there is some risk the problem appears in other places as well.
