Mainline (would be 4.8.0) is fine and I can't even compile the testcase with

4_6-branch, thus this isn't a regression.



In the future, please do your best to reduce the size of your testcase: in

99.999 % of the cases, 2-3 KB are enough.

Thanks for checking this, will also try 4.8.0 at some point. We have hundreds

of tests using C++11 extensively and this was the only one exposing this

warning. This is mostly generated code and I tried to reduce it further, but

when I reduced it further the warning was gone. I didn't had a clue why it

could be triggered, that lack of knowledge prevented me from reducing the test

case further

Lowering optimization from -O3 to -O2 removes the warning
