--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
One more test-case with a bit different BT:
$ cat ice.ii
namespace {
class a typedef b;
class a {};
} // namespace
class c {
struct C {
b d;
};
C e() const;
};
c::C c::e() const {
C g;
struct h {
C g;
h(C *) {}
} f(&g);
}
$ g++ ice.ii -O2 -flto=8 -g -shared
ice.ii: In member function ‘c::C c::e() const’:
ice.ii:17:1: warning: no return statement in function returning non-void
[-Wreturn-type]
}
