[cfe-dev] Function return not catching the undefined behavior

[phy coder via cfe-dev]

I'm not sure if this is undefined behavior or not and it may be discussed
before or not. I was testing some random code snippets to try
"-fsanitize=undefined" but in this example:

#include<iostream>

char func(int a, int b) {
int sum = a+b;
return sum ;
}

int main() {
int n;
char s = func(100,100);
int t = func(100,100);
std::cout << "hello" << s << t;
return 0;

}

I was expecting some kind of undefined behavior here because of some
overflowing the char return type with integer return type. But
"-fsanitize=undefined" is not able to catch this . And I got the output
this : hello�-56
Kinda weird for me .
