--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I think we can probably do this to stop the test failing:
--- a/gcc/testsuite/g++.dg/cpp2a/concepts-pr67774.C
+++ b/gcc/testsuite/g++.dg/cpp2a/concepts-pr67774.C
@@ -1,5 +1,4 @@
// { dg-do compile { target c++20 } }
-// { dg-additional-options "-fconcepts-ts" }
#include <type_traits>
#include <utility>
Because that flag was present to enable concepts support, but concepts are
always enabled for c++20 now, and it gets run with -std=c++2a
But the FE bug still needs to be fixed.
