Reduced testcase:
struct JSContext;
struct JSObject;
class WorkerHooks {
virtual JSObject *newGlobalObject(JSContext *cx) = 0;
};
int
shell(JSContext *cx, int argc, char **argv, char **envp)
{
class ShellWorkerHooks : public WorkerHooks {
JSObject *newGlobalObject(JSContext *cx) { }
};
ShellWorkerHooks hooks;
}

------- Comment #3 from rguenth at gcc dot gnu dot org 2010-07-23 18:24 -------
Without LTO the limbo DIE has a non-NULL get_AT_ref (die,
DW_AT_abstract_origin),
a DW_TAG_subprogram. For some reason that doesn't get created with LTO
(not easy to follow why).
More reduced testcase:
struct Base { ~Base (); };
void fun(void) { struct Deriv : Base { } x; }

Similar testcase from PR43898:
void bug() {
struct Class {
Class(int a) {}
virtual void f() {}
};
Class a(0);
}
