As I was wondering whether there could not be a better way to prevent the warning, I tried to reproduce the case. I've tried gcc 4.8.3 as well as 4.9.1 and gcc 4.7.4, and none of them emits the warning above.
Lukasz, where can I find the toolchain that you are using and which emits the warning?
Amicalement,
