The question of the asymptotic behaviour of the spectrum of the boundary value problem \begin{equation*} -y''-\lambda\rho y=0, \qquad y(0)=y(1)=0, \end{equation*} is considered, where $\rho$ is a function in $\mathring W_2^{-1}[0,1]$ with arithmetically self-similar primitive function. It is not assumed here that the weight $\rho$ has a constant sign. The theoretical results obtained are illustrated by the data of numerical calculations. Bibliography: 10 titles.
