<pre>Test illustrating the leak:
class B;
class A {
B* b;
public:
A() : b(0) {};
~A();
void SetB(B* bb) {
b = bb;
}
};
class B {
public:
B(A& a) {
a.SetB(this);
}
};
A::~A() {
if (b)
delete b;
}
void f() {
A a;
new B(a);
} <----- false-positive leak report; Memory is freed inside ~A();
The following trick is common for LLVM/lib/Target/* and LLVM/lib/MC/*.</pre>
