In the code below, ddd::test() gets referenced from ttt<ddd>::test() (called
from ccc::test(), in turn called from test(ccc&)) prior to the definition of ddd
being visible. 3.3.x (unless exceptions were disabled) properly rejected this code.
class bbb {
public:
void test();
};
template<typename T> class ttt {
T*p;
public:
void test() { p->test(); }
};
class ddd;
class ccc {
ttt<ddd> m;
public:
void test() { m.test(); }
};
void test(ccc&r) {
r.test();
}
class ddd : public bbb {};
