So the problem is really if (optimize_loop_for_size_p (loop)) . I think you need to figure out why that is returning true. I can see why to some extent as we have a pointer comparison against a NULL pointer; we assume the pointer will not be null when duplicating the loop. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42720
