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.
