--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:

$ cat vcldemo.ii
namespace osl {
class Thread {
public:
  virtual ~Thread();
  virtual void join();
};
} // namespace osl
class SimpleReferenceObject {
protected:
  virtual ~SimpleReferenceObject();
};
class Thread : SimpleReferenceObject, osl::Thread {
public:
  osl::Thread::join;
};
class RenderThread : Thread {
  RenderThread() { join(); }
};

and a nice backtrace:

$ /home/marxin/Programming/gcc2/objdir/gcc/xgcc -B
/home/marxin/Programming/gcc2/objdir/gcc -O0 -Wall -fstack-protector-strong -c
