I put some analysis here http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00456.html It is latent bug in C++ FE using stale source_location. Prior my change the error came on different location based on optimization flags and -flto. After my change it is consistently wrong ;) Sadly i am not sure how to get correct location within the mangling hook and where it is supposed to point.
