[Bug c++/40749] New: g++ doesnt report missing return if return is of type const

[mfribeiro at gmail dot com]

This code below wont generate a warning for function a(). Compiled with -Wall.
If you remove the const from the return, it will work.


class A {
public:
};

const A a() {
}

int main() {
  A b = a();
}

[Bug c++/48829] New: g++ no warning initializing a variable using itself

This code issues a warning:

g++ -Wall
int i = 5 + i;
warning: ‘i’ may be used uninitialized in this function

This code does not:
string s = string("str") + s;

Neither this:
string s(string("str") + s);

Shouldnt the 2 last ones issue warnings too?
