When is an unnamed automatic variable destroyed?

[Steven T. Hatton]

In this code, when will (should) Xfromer::release be called?
struct C {
C(const char* c) { f = Xformer::xform(c); }
~C() { Xformer::release(f); }
const F* get() const { return f; }
F* f;
};

void fun(const char* c) {
F* foo = C(c).get();
bar(foo);
baz();
}

struct C {
C(const char* c) { f = Xformer::xform(c); }
~C() { Xformer::release(f); }
const F* get() const { return f; }
F* f;
};

void fun(const char* c) {
F* foo = C(c).get();

The temporary that is used in the expression to initialise 'foo' will be
destroyed at the end of 'foo's initialisation. 'Xformer::release' should
be called as part of the destruction of the temporary, right after 'foo'
is initialised.

bar(foo);
baz();
}

Uh... Did you mean to supply some explanation to those links?
