as you can see this was a problem reported by your truly :)

infact, its an issue seen for gcc4.8 and arm architecture thus far seems to work fine for x86. It also works ok with gcc 4.7 on arm but given that c++11 is new there is something to fix there for arm. I hope linaro toolchain group has taken a note of this issue. as you can see its not only seen in Linaro toolchain which was my initial thought. but its also prevalent in upstream 4.8 gcc. I haven’t tested gcc 4.9 may be its fixed there.
