Considering your patch and my investigation though, it's not showstopper. In fact, there are a few places that call memmove, all of them aren't on "common path". However, I would consider that common path certainly depends on the way Linux is used. I may imagine the configuration where the bug may trigger. Perhaps, eliminating that known "horror fix" (you know) is more important. Regards, Gleb.
