--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
(In reply to Christopher Friedt from comment #6)
> It's supported OOTB in `clang++` but fails in `g++`.

Nobody is disputing that, but Clang supports lots of things that aren't val=
id
in C++ and aren't supported by G++, and G++ supports things that aren't val=
id
in C++ and aren't supported by Clang. That's not a bug.

Yes, and it's not valid C++.

I commented explaining that it's not in the C++ standard, and followed up in
the github issue where the real bug is. That's hardly "without consideratio=
n".
I've shown how to fix your C++ code to make it valid in C++11, and pointed =
out
a problem in your C code using _Generic. I didn't have to do any of that, a=
nd I
certainly won't bother doing so again.=
