Hi All,

since 1st of February i get an undefined symbol to

U std::_Bind_simple_helper<void
(std::thread::*)()<std::reference_wrapper<std::thread> > >::__type
std::__bind_simple<void (std::thread::*)(), std::reference_wrapper<std::thread>
>(void (std::thread::*&&)(), std::reference_wrapper<std::thread>&&)

within libstdc++.so.6.0.17. Does anyone know why?

Last gcc svn revision i tried was 183468.

Mario.
