Octave 4.2:
Matlab 2016a
The behaviour looks compatible to me, I think we can close this item.

Let me explain better the second point of the previous post: that warning appears when I set both AbsTol and RelTol to zero, because in function AbsRel_Norm there is an element by element division and the denominator depends on these two parameters. So for any index of the vectors AbsRel and AbsTol, there must be at most one element equal to zero.
I have checked the latest version of Matlab and if I set the options using opt=odeset('AbsTol', 0, 'RelTol', 1e-3) I get:
or, if I set RelTol to zero:
In the latest version of Matlab it's not allowed to set one of these options to zero, so this may not be considered a bug anymore.
