--- Comment #7 from Paolo Carlini <paolo.carlini at oracle dot com> --- Unfortunately, I'm afraid it's a real issue. Note the test has -Wno-error=narrowing, not -Wno-narrowing. Thus the pedwarn at typeck2.c:962 returns true and ok remains false while we only emitted a warning and the compilation goes on. In other terms we have a variant of c++/65858. It may work to simply set ok = true unconditionally, after all we do the same for the previous pedwarn and in this case we are simply forcing -pedantic-errors, something that can happen for any other pedwarn as a normal user provided switch.
