------- Comment #7 from manu at gcc dot gnu dot org 2010-06-11 13:07 ------- He is referring to a testcase like:
template<typename T, T C> void f() {
struct A {
T x;
};
T y = 42;
A a = { y + C };
}
int main() {
f<int,1>();
f<char,1>();
}
So, we warn for T == char but not for T == int. I know that the standard
considers differently narrowing and overflow but the difference is still
surprising.
