Erdős problem 906

Is there an entire non-zero function f:CCf:\mathbb{C}\to \mathbb{C} such that, for any infinite sequence n1<n2<n_1<n_2<\cdots, the set {z:f(nk)(z)=0 for some k1}\{ z: f^{(n_k)}(z)=0 \textrm{ for some }k\geq 1\} is everywhere dense? The literal question is trivial for polynomials, so the claims address the transcendental entire case, in the affirmative.
