Basically, the GC finds the set of dead objects in an
unspecified order, which from the POV of user code should be
regarded as random and unpredictable. Consider an object c of
class C:
```
class C {
A a;
B b;
this(A _a, B _b) { a = _a; b = _b; }
~this() {
}
}
auto a = new A;
auto b = new B;
auto c = new C(a, b);
```
When c goes out of scope, a and b are still referenced by c,
but are no longer reachable from the rest of the program. The
order in which the GC finds dead objects is not specified
Is it possible that during stack unwinding the GC kicks in and
destroys an exception object before it is caught?
