@kevinkreiser
Thanks for the quick an detailed response! I played around with your example for a while but unless I add a + operator to the bar struct similar to this in foo, it's not compiling. I now installed gcc5 just to be able to verify it should compile.

Your code compiles with gcc6 with gnu++98 and c++98 when changing the curly braces to normal parentheses, although, some warnings appear (warning: inheriting constructors only available with -std=c++11 or -std=gnu++11). It does produce an out file which is executing correctly. Odd stuff.

that is extremely odd. we were basically making use of constructor inheritance which became available in c++11... very confusing! ill try this out on a newer ubuntu (hopefully newer gcc) to see if that shows anything...

given that you are on arch, are you compiling gcc from source? if so is it possible there is some kind of gcc configuration flags that make this happen? sorry im really not an expert on arch!

I have the same problem with Ubuntu 17.04:

Have you any solutions? Otherwise, I try to change your source.
