Hi!
When using this the [[ noreturn ]] attribute like this: - void f [[
noreturn ]] (); - I get a warning that reads:
warning: 'noreturn' function does return
( http://www.stroustrup.com/C++11FAQ.html#attributes )
What can I do to remove this warning?
I don't see a warning for the example with GCC 4.8, 4.9, or
5.1. If you do, it might help if you posted the version of
GCC you're using and the command line options (for example,
like I did below). You could also check Bugzilla for known
noreturn bugs (though I couldn't find anything relevant).

$ cat t.cpp && g++ -v && g++ -Wall -Wextra -c -pedantic -std=c++11 t.cpp
void f [[ noreturn ]] () { throw "error"; }
