Re: GNU Emacs crashes with longlines-mode and outline-mode

A reduced test case below. I am still looking for what outline mode does
that triggers the crash. Setting up the invisibility spec to show
ellipses, creating an overlay at the end of the buffer and making it

ellipses might have an idea where to look?

Some text. Some text that must be longer than one line, to test
