--- Comment #2 from Daniel Krügler <daniel.kruegler at googlemail dot com> 2013-04-11 18:05:18 UTC --- Here is my suggestion for a possible test, to be compiled with flags -std=c++11 -Wall -W -pedantic //------------------------- #define copy_exception k42; #include <exception> #include <future> //------------------------- This code should be accepted, but chokes currently (as expected).
