This seems to have been fixed, presumably by changes in IntervalArithmetic.jl
:
julia> rts = roots(x->x^2 - 2, big(-∞..∞), 1e-70)
2-element Array{Root{Interval{BigFloat}},1}:
Root([1.41421, 1.41422]₂₅₆, :unique)
Root([-1.41422, -1.41421]₂₅₆, :unique)
julia> diam.(interval.(rts))
2-element Array{BigFloat,1}:

First diameter is 0, which is a bug, since it is not an enclosure of sqrt(2).
