Maybe it's already fixed. Nope, it isn't. So the problem comes when you copy a file over itself. This indeed crashes here aswell. This points to a bug in the ramfs implementation which should be fixed. Also there's another bug in 'cp': copy_file should recognize when source and destination are the same file and report an error in this case.
