That's how std::thread works. You need to use std::ref to pass by reference. The most recent explanation I've given is at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68784
I am also somehow surprised about the real need for rvalue reference forwarding for the arguments (unlike for the function object itself - my reasoning too is that the programmer should know when to use references), but you are right that this is about the standard.
Thanks a lot for your reply.
