I’ve tried with RawTherapee, and the mountain line do show fringes, mostly in the reds, but also in the greens (mostly on the left part).
Most surely you already will be aware, but to my knowledge Chromatic Aberrations and Fringes are different kinds of aberrations (CAs showing blue and yellow lines, while fringes mostly purple, but green too). Thus, there are different tools to correct those different aberrations.
Can’t say anything about darktable, but with a moderate use of the Defringe tool in RT5.8, the offending colors are gone.
