I concur with comment 11 that the original problem doesn't occur anymore in
4.4.4 (it still occurred in 4.1.2). Since the variation in comment 4 was also
patched, and being unaware about the protocol, I'll go out on a limp and try to
close this.

[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
