I was wrong that this issue doesn't exist on emacs 26.x (my mistake was
that I was loading native line numbers automatically in my config if emacs
version >+ "26.0"). It seems to exist in a different form if I load nlinum.

I got a SIGABRT on emacs 26.0.90:

Thread 1 "emacs" received signal SIGABRT, Aborted.
