[Bug c++/25973] New: Wrong warning: control reaches end of non-void function

[ssomers at opnet dot com]

-Wall produces warning on second function, not on slightly simpler first
function.

struct C {
    C() { }
    ~C() {}
};

int fine(int p) {
    C c;

    if (p) {
        if (p == 4) {
            return 1;
        } else {
            return 2;
        }
    } else {
        return 3;
    }
}

int foul(int p) {
    C c;

    int pcopy = p;
    if (pcopy && p) {
        if (p == 4) {
            return 1;
        } else {
            return 2;
        }
    } else {
        return 3;
    }
}

Probably a duplicate of 20624 or so.  I can't access newer version right now.
Occurs in 4.0.1, 4.0.0, not in 3.4.5
