roo was a typo for too. The r and t are next to each other on the standard
qwerty keyboard.
Anyways I think the warning should be reworded to say might be writing instead
of a definite. There is another bug talking about the wording too.
Also the way I read the code in both the original and reduced testcase, without
knowing how components' range, there could be a buffer overflow.
