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.
