Weird that I haven't seen this with a host g++ >= 4.7 (4.7.2-2); I've certainly built post-r210931 (post-2014-05-26) for example r212486, but obviously so, thanks. I see the warning in my logs but -Werror wasn't isn't used and I didn't pay attention. Did something change more recently re: building with -Werror? brgds, H-P
